发明名称 Liquid crystal display
摘要 A liquid crystal display apparatus having a circular polarizer (composed of a linear polarizer and a retardation film), a scattering layer and a liquid crystal display which are stacked one upon another. The liquid crystal display has a chiral nematic liquid crystal layer between substrates, and electrodes and aligning layers are provided on mutually opposite surfaces of the substrates. The chiral nematic liquid crystal changes between a planar state and a focal-conic state in accordance with a voltage applied thereto through the electrodes. When the liquid crystal is in a planar state, light reflected by the electrode formed on the substrate located farther from an observing side is absorbed in the circular polarizer, and a black display is made. When the liquid crystal is in a focal-conic state, light reflected by the electrode formed on the substrate located farther from the observing side passes through the circular polarizer, and a white display is made. In this moment, the light reflected by the electrode is scattered by a scattering layer, and the directivity of the reflected light is weakened.
