Abstract: In a liquid crystal display device according to the present invention, an upper end portion of a lamp housing is fixed on a main supporter so that the lamp housing can be made to face a side edge of a light guide. Light that can cause bright lines is eliminated or minimized through absorption or scattering by a main supporter. The main supporter is also thermally insulating and is placed between the lamp housing and a liquid crystal panel. Further, a thermally conducting bottom cover is placed under the backlight. Therefore, heat generated from the lamp is effectively channeled away from the light guide to prevent liquid crystal panel deterioration. Still further, although the upper and lower surfaces of the light guide is tightly fit between the lamp housing and the main supporter, wrinkles on a sheet reflector are prevented because the sheet reflector is not stacked between the lamp housing and a lower surface of the light guide.

Abstract translation: 在根据本发明的液晶显示装置中，灯壳的上端部固定在主支架上，使得灯壳体能够面对光导的侧边缘。 通过主支架的吸收或散射消除或最小化可引起亮线的光。 主支架也是隔热的，并放置在灯壳和液晶面板之间。 此外，将导热底盖放置在背光下。 因此，从灯管产生的热量有效地从导光体引出，以防止液晶面板劣化。 此外，虽然导光体的上表面和下表面紧密地配合在灯壳体和主支架之间，但是由于纸反射器不堆叠在灯壳体和光的下表面之间，因此防止了纸反射器上的褶皱 指南。
