The liquid crystal panel 121 and the backlight unit 123 are integrated by being hooked in the recess. The unit in which the liquid crystal panel 121 and the backlight 123 are integrated is fixed to the metal chassis 6 with screws 124.

  The present invention will be described in detail with reference to FIG. FIG. 1 is a cross-sectional view of the back side of a camera to which this embodiment is applied. In FIG. 1, a backlight unit 123 holds a light emitting diode (not shown) as a light source, a backlight 123, and a liquid crystal panel 121. The backlight frame 123a, the light guide plate 123b that converts local light from the light emitting diodes into surface light emission, and the resin spacer that receives the liquid crystal panel are included as main components. The backlight frame 123 is formed by bending from a single metal plate, and the light emitted by the light emitting diode is transmitted from the backlight unit 123 to a surface other than the liquid crystal panel 121, despite being thin. Leakage is reduced. The light obtained by the backlight unit 123 enhances the visibility of the display on the liquid crystal panel 121. On the external side of the liquid crystal panel 121, there is a substantially colorless and transparent window member 4 fixed to the back cover 3, and light emitted from the backlight 123 is irradiated to the outside via the window member 4. However, since the entire window member 4 is almost colorless and transparent, light is guided to the entire window member 4 (for example, up to a portion 4a which is an end surface of the window member 4). At this time, if the shielding object is not present between the end portion of the window member 4 and each hole such as the hole 3b exposing the operation button 82 provided on the back cover 3, light is not desired to leak. Light leaks from the holes 3b and the like, which deteriorates the appearance quality. In order to prevent this light leakage, the bent portion of the backlight frame 123a is extended to a position where it covers the end surface 4a of the window member 4, and is unnecessary led to the end portion 4a of the window member 4 by the backlight frame 123a. Shields light.

  In the present embodiment, the backlight unit 123 is fixed to the metal chassis 6 with screws 124, but the fixing target is not limited to the metal chassis 6, but any component such as the lens barrel unit 11 or the back cover 3. Also, the fixing method is not necessarily fixed by the screw 124, and it may be fixed by being hooked on the nail, or both the screw 124 and the nail hook may exist. In addition, the camera is taken as an example, but the scope of application is not limited to the camera, and it can be applied if it has a display unit. It extends to equipment.

  Since the basic structure of the second embodiment of the present invention is the same as that of the first embodiment, only the different configuration will be described. FIG. 4 is a cross-sectional view of the back side of the camera to which the present embodiment is applied. As shown in FIG. 4, a foaming elastic member 131 is attached to the back side of the backlight frame 123a. The backlight frame 123a is fixed by a step screw 125 so as to be movable only in the vertical direction as viewed in FIG. The foamed elastic member 131 exists in a compressed state by the backlight frame 123a and the metal chassis 6 when the back cover 3 is assembled in the camera body, and biases the backlight frame 123a to the exterior side. I am letting. At this time, since the distance between the tip of the standing bent portion of the backlight frame 123a and the back cover 3 is set closer than the distance between the liquid crystal panel 121 and the window member 4, the standing bent portion of the backlight frame 123a is set. The place where the tip comes into contact with the back cover 3 becomes a stopper, and the effect of shielding and covering unnecessary light by covering the end face 4a of the window member 4 is enhanced.

  In this embodiment, the backlight frame 123a is urged by the foamable elastic body 131. However, as long as the member has elasticity, it can be applied even to a spring member made of a rubber member, metal, or resin. Easy. Further, as in the first embodiment, the backlight unit 123 is not necessarily fixed to the metal chassis 6, and may be any component such as the lens barrel unit 11 and the back cover 3. It is not necessary to fix with the screw 125, and it may be fixed by hooking on the nail, or both the step screw 125 and the nail hook may exist. The applicable range is not limited to the camera, but can be applied if it has a display unit, and extends to various devices such as a video camera, a television, a mobile phone, a copying machine, a printer, a FAX, and an electronic notebook. .

  In the third embodiment of the present invention, the basic structure is the same as that of the first embodiment and the second embodiment, so only the different configuration will be described. FIG. 5 is a cross-sectional view of the back side of the camera to which the present embodiment is applied. As shown in FIG. 5, a foaming elastic member 131 is attached to the back side of the backlight frame 123a. The backlight frame 123a is fixed by a step screw 125 so as to be movable only in the vertical direction as viewed in FIG. The foamed elastic member 131 exists in a compressed state by the backlight frame 123 and the metal chassis 6 when the back cover 3 is assembled in the camera body, and biases the backlight frame 123a to the exterior side. I am letting. At this time, since the distance between the liquid crystal panel 121 and the window member 4 is set closer than the distance between the tip of the bent portion of the backlight frame 123 a and the back cover 3, the liquid crystal panel 121 contacts the window member 4. The contact portion serves as a stopper, and the liquid crystal panel 121 and the window member 4 are in contact with each other, reducing the air layer existing between them, and improving the appearance visibility (the air existing between the liquid crystal panel 121 and the window member 4). Since the layer has the effect of irregularly reflecting external light, it is preferable that there is no air layer in order to improve the appearance visibility. However, by adopting this structure, a gap remains at the tip of the standing bent portion of the exterior cover 3 and the backlight frame 123a, and a sufficient effect of shielding unnecessary light cannot be obtained. However, the exterior cover 3 has a recess 3a, and when the liquid crystal panel 121 and the window member 4 are in contact with each other, the tip of the bent portion of the backlight frame 123a is formed in the recess provided in the exterior cover 3 as shown in FIG. Therefore, even if a gap remains between the exterior cover 3 and the backlight frame 123a, light can hardly be leaked.

  In this embodiment, the backlight frame 123a is urged by the foamable elastic body 131. However, as long as the member has elasticity, it can be applied even to a spring member made of a rubber member, metal, or resin. Easy. Further, as in the first and second embodiments, the fixing target of the backlight unit 123 does not necessarily need to be the metal chassis 6, and may be any component such as the lens barrel unit 11 and the back cover 3. However, it is not necessary to fix with the corrugated screw 125, and it may be fixed by being hooked on the nail, or both the corrugated screw 125 and the nail hook may exist. The applicable range is not limited to the camera, but can be applied if it has a display unit, and extends to various devices such as a video camera, a television, a mobile phone, a copying machine, a printer, a FAX, and an electronic notebook. .
