    • A liquid crystal display panel having a backlight for providing high brigess, uniformity of illumination intensity, high efficiency, and long battery life, and which can be manufactured at a low cost. The display device includes a liquid crystal display panel, a light source for illuminating the liquid crystal panel, a light passage member which can be formed of a transparent material disposed between the liquid crystal panel and the light source. The light source inlet side of the light passage member is formed with a recess with the thickness being reduced at the region diametrically opposed to the light source. A light reflecting member reflects light from the light source. Within the photoconductor, two or more of the wedged shaped photo conductor can be used for increased area of coverage.
    • 一种液晶显示面板,其具有提供高亮度,均匀的照明强度,高效率,长的电池寿命的背光源,可以低成本地制造。 显示装置包括液晶显示面板,用于照亮液晶面板的光源,可以由设置在液晶面板和光源之间的透明材料形成的光通过构件。 光通路构件的光源入口侧形成有与光源径向相对的区域的厚度减小的凹部。 光反射部件反射来自光源的光。 在光电导体内,两个或多个楔形光导体可用于增加覆盖面积。
