摘要： In a liquid crystal apparatus in which a white light of a fluorescent tube corresponding to a linear light source repeats plural times of diffusions and reflections between a reflection sheet and a diffusion plate, and is thereafter input as a back light to a liquid crystal panel corresponding to a display screen, an object of the invention is to make it possible to secure a brightness uniformity even if the liquid crystal apparatus is thinned. It is possible to prevent a brightness unevenness caused by a short distance from the reflection sheet to the diffusion plate, by preventing a deformation (a deformation which is convex toward the fluorescent tube) of the diffusion plate due to a thermal expansion of the diffusion plate caused by a heat generation of the fluorescent tube, by arranging at least one pin mold hold so as to support a portion near an approximately center of the diffusion plate.

In this configuration, the reflection properties are different in the vicinity of the end portions and as the center portion of the opening for illumination, and the brightness increases in the vicinity of the end portions of the backlight device, so that an area in band form where the brightness is inconsistent can be prevented from being created in the end portions of the display device.

摘要： An object of the present invention is to provide a liquid crystal display device having a light guide plate that is capable of providing improved liquid crystal display performance without generating a striped image. The liquid crystal display device includes a light guide plate, which illuminates a liquid crystal panel from its rear surface, and light sources, which shed a light ray on the light guide plate. The rear surface of the light guide plate is separated into a plurality of rear surface divisions by concave grooves. The light sources can adjust the brightness of each rear surface division. The display performance of the liquid crystal panel is improved by individually managing a plurality of regions of the liquid crystal panel, which correspond to the rear surface divisions, and darkening a rear surface division that corresponds to a region where the black color is predominant.
