Abstract:
1. An STN liquid crystal display comprising. a back light using a monochromatic light source for emitting monochromatic light; and a liquid crystal display cell including first and second transparent substrates facing to each other, first and second transparent electrodes formed on facing surfaces of said first and second transparent substrates, respectively, first and second alignment films formed above said first and second transparent substrates, covering said first and second transparent electrodes, respectively, a liquid crystal layer sandwiched between said first and second transparent substrates, and first and second polarizers disposed on outer surfaces of said first and second transparent substrates, wherein twist angle of said liquid crystal layer is 95° to 170° or 200° to 280°, a first angle between an alignment direction of liquid crystal molecules in said liquid crystal layer contacting said first transparent substrate and a polarization direction of said first polarizer and a second angle between an alignment direction of liquid crystal molecules in said liquid crystal layer contacting said second transparent substrate and a polarization direction of said second polarizer are each larger than 0° and smaller than 90°; and sum of said first and second angles is 90°±7°.
