2. Description of the Related Art A conventional display device, which is made thin by using a PDP or the like, and which easily supports a stand-mounted type or a wall-mounted type, is particularly designed for heat generated inside the device. There is a problem with the discharge method of the above, for example, JP-A-7-3221.
As shown in Japanese Patent Publication No. 71, there is a display device in which heat generated inside the device is conducted to a frame which is a structural body and is radiated from a radiation fin on the outer periphery which is integrally formed with the frame.

FIG. 4 shows a structure of a conventional display device. By fastening a display body 14 such as a PDP which is a heating element and a signal unit 15 to a frame 17 which is a structural body using fastening members 16a16b, respectively. The heat generated inside the display device is conducted to the frame 17,
The heat radiation fins 18 are integrally formed on the outer periphery of the heat dissipation fin 7.

[0004]

As described above, regarding the emission of heat generated inside the display device, the problem is how to conduct the heat from the heat generation source and release it to the outside.
For a display device such as P in which the display body itself is a heating element, one of the problems is how to release the temperature of the surface of the display body to the outside. In particular, it is difficult to suppress the temperature rise of the display body because the display body (viewer side) of the display body cannot have a structure for conducting the generated heat to the frame or the like.

[0005]

In order to solve the above-mentioned problems, a display device of the present invention comprises a panel-shaped display body, a frame-shaped frame for mounting the display body on the front side, and a frame-shaped frame mounted on the frame. It comprises a front panel that covers the front surface of the display body, and a rear panel that is attached to the back surface of the frame, and a space is provided between the front surface portion of the display body and the front panel, and at least above and below the front panel or the rear panel. It is characterized in that holes for heat dissipation are arranged.

According to the present invention, in a structure such as a PDP in which the display body itself is a heating element and a structure for conducting heat to a frame or the like cannot be arranged on the display side (front side of the display device) of the display body. Thus, it is possible to provide a display device capable of preventing heat from staying on the surface of the display body by convection of air and suppressing an increase in temperature of the display body.
