ABSTRACT:
A reflective type liquid crystal display device including a layer of liquid crystal having a light scattering property such as a polymer dispersed type liquid crystal or a phase change type liquid crystal. The layer of liquid crystal is arranged between first and second plates having transparent electrodes, respectively, the first plate being transparent and the second plate having a reflecting layer. A color filter including red, green, and blue color portions and a black color portion, and an internal transparent plate having a thickness to provide a sufficient distance between the layer of liquid crystal and the color filter to diffuse the appearance of the color filter viewed through the scattering liquid crystal in the light scattering mode are also placed between the first and second plates. The layer of liquid crystal having light scattering property is brought into a light scattering mode to produce a white display when the voltage is not applied, and into a transparent mode to produce a color display and a black display when the voltage is applied.
