JP 2005-37814 A

  In the above apparatus, since the frame 1 accommodates the light guide plate 9 and the like, there is a first drawback that the frame 1 becomes a large component and the cost becomes high. In order to eliminate this drawback, the present inventor manufactured a liquid crystal display device having the function of the frame 1 with a frame body without providing the frame 1.

  That is, a heat radiating plate, a reflecting plate, and a light guide plate were sequentially arranged on the mounting portion of the frame body, and a liquid crystal cell was disposed on the upper mounting portion of the frame body. In order to reduce the size of the apparatus, the upper mounting portion is disposed above the light guide plate. Therefore, at the time of assembling, the liquid crystal cell 2 must be arranged at the bottom, and the frame, the light guide plate, the reflecting plate, and the heat radiating plate must be assembled thereon in order. As a result, there is a second drawback that the liquid crystal cell is easily damaged.

  In view of the above-described drawbacks, the present invention provides a liquid crystal display device that is less likely to be damaged during assembly, is inexpensive, and is downsized.

  In order to solve the above-described problem, in the present invention of claim 1, the liquid crystal cell and the liquid crystal cell are disposed on the back side, and are formed in a frame shape having a placement portion and a side portion on a plurality of sides. A frame, a heat sink, a reflector, and a light guide plate arranged in order on the placement unit, a light source arranged to face a side surface of the light guide plate, and at least one side formed on the frame A support body disposed on the side portion, wherein the support body is formed with an upper placement portion located above the light guide plate, and at least one side of the liquid crystal cell is disposed on the upper placement portion. It was done.

In the present invention of claim 2,
The frame is connected to the side part, and a wall having a step part is partially formed. The support part is partially formed with a collar part, and the collar part is engaged with the step part. .

  In this invention of Claim 3, in the said support body, it connected to the said upper mounting part in order, and the wall part and the said collar part were formed in substantially crank shape.

  According to the fourth aspect of the present invention, in the frame body, a hole is formed in the vicinity of the wall, the wall is formed with a thick part and a thin part, the step part is formed at a boundary between both parts, and the hole Was formed so that the collar part of the support could pass through.

  In the present invention of claim 5, in the frame, the side on which the wall is formed is provided at a position facing a side located in the vicinity of the light source.

  In this invention of Claim 6, the said wall is formed in the outer side rather than the said side part, and the inner surface of the front frame formed in the substantially U shape and partially is the upper surface formed in the said wall. , Arranged in contact with or close to the side surface and the bottom surface.

  Since the frame body and the support body are provided separately as in the first aspect, the liquid crystal cell is not assembled with the liquid crystal cell facing down as in the prior art, so that the liquid crystal cell is not damaged during the assembly. The support is formed on the side of one side of the frame and is a small component, so the cost is low. Further, since the upper mounting portion of the support is located above the light guide plate, the apparatus can be miniaturized.

  As described in claim 2, since the flange portion of the support body is engaged with the step portion of the frame body and the support body is disposed on the side portion of the frame body, the support body is securely fixed to the frame body. The

  According to the third aspect of the present invention, since the support part has a wall in which the upper mounting part, the wall part, and the flange part are formed in a crank shape, the support body is formed thin overall. As a result, since the sink is less likely to cause sink marks (deformation during resin molding), the support is less likely to be deformed.

  As in claim 4, since the hole of the frame body is formed so that the collar portion of the support body can pass, when the support body is moved downward from above, the support body is Easy to install.

  As described in claim 5, since the side on which the wall of the frame is formed is provided facing the side located in the vicinity of the light source, the length from the end of the light source to the end of the opposing frame is reduced. And the device can be miniaturized.

  Since the inner surface of the front frame is disposed in contact with or close to the upper surface, side surface, and bottom surface of the wall as in claim 6, the front frame is surely and properly positioned with respect to the frame body. It is fixed with. Also easy to assemble.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to examples and drawings.
