    • A liquid crystal display has s a liquid crystal cell having a front surface serving as a viewing-side surface and a back surface, a reflecting film is attached to the back surface of the liquid crystal cell, and a light guide panel having a first major surface provided with minute irregularities and a second major surface finished in a smooth flat plane is disposed on the front surface of the liquid crystal cell with the second major surface thereof finished in a smooth flat plane in contact with the front surface of the liquid crystal cell. A light source is disposed beside aside surface of the light guide panel. When the liquid crystal display is used in a dim environment, the light source is turned on. Light emitted by the light source is guided and scattered toward the reflecting film by the light guide panel, so that the light can be transmitted efficiently by the light guide panel and the liquid crystal cell to the reflecting film.
    • 一种液晶显示器,具有作为观察侧面和背面的正面的液晶单元,反射膜附着在液晶单元的背面,具有第一主面的导光板 具有微小的不规则性,并且在光滑平面上成形的第二主表面设置在液晶单元的前表面上,其第二主表面在与液晶单元的前表面接触的平滑平面内完成。 光源设置在导光板的旁边。 当液晶显示器在昏暗的环境中使用时,光源被打开。 由光源发射的光被导光板引导并散射到反射膜,使得光可以通过导光板和液晶单元有效地传输到反射膜。
