Liquid crystal display device comprising at least one groove having an end portion that stops short of the non-adjacent opposite side surfaces and extends in a direction perpendicular to the non-adjacent side surfaces
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.
摘要（中）：

本发明的目的是提供一种具有导光板的液晶显示装置，其能够在不产生条纹图像的情况下提供改进的液晶显示性能。 液晶显示装置包括从其后表面照射液晶面板的导光板和在导光板上散开光线的光源。 导光板的后表面由凹槽分隔成多个后表面。 光源可以调节每个后表面划分的亮度。 液晶面板的显示性能通过单独地管理与后表面划分相对应的液晶面板的多个区域，并使与黑色主要区域对应的后表面分割变暗来提高。
