Abstract

PURPOSE:To improve the radiation of a light source by providing a radiating means which includes a metallic layer adhered to the circumferential edge of the back surface of a liquid-crystal device. CONSTITUTION:The metallic layer 12 is adhered to the back-surface circumferential edge of the liquid-crystal display device 11. The metallic layer prevents a local rise in temperature at the part opposed to the electric bulb of the light source to equalize temperature, obtaining enough effect. The metallic layer is connected thermally to a holder and a heat conductive member to obtain more excellent effect.

An incandescent light bulb is used as the light source for the display device of the back blade tip technique on steaming, which requires less installation space, but this (second) has a problem of heat dissipation during lighting. Although it generates less heat, its usage is quite limited because it takes up a large space, the lighting circuit is complex, and the lighting power source generally requires AC.

Therefore, there are measures to prevent heat generation by using one incandescent lamp.1. As shown in FIG.
There is a disadvantage that it requires a middle stage, such as providing a 2-stage space, or requires a large space. . There is also a way to reduce the heat generated by γIJ/1 at a low power supply (7), but it has the drawback that the display surface becomes dark and unclear.In the end, the heat emitted from the light bulb is 2, and the heat generated by 1 tatami mat + 111 : On the scattering board, the 11th display on the crystal display shows the shortcoming of 7.7L of rice, which is 7.7L.
