ABSTRACT:
In a color liquid crystal display device of the invention, light-blocking members of predetermined configurations (characters, graphics etc.) are disposed on the surface of one side of a liquid crystal display element, that is to say the surface on the side opposite to the light source, and the predetermined configurations are displayed on the color liquid crystal display device by blocking the light from the light source with the light-blocking members. Further, a light-scattering plate is disposed between the light source and the liquid crystal display element, or between the liquid crystal display element and the light-blocking members. It is possible to allow transmission of a part of the light blocked by the light-blocking members by scattering the light which is transmitted through the liquid crystal display element with the arrangement of the light-scattering plate. Therefore, around the periphery of the light-blocking members, the color balance of the transmitted light breaks down and only a specific color of light is transmitted, thereby preventing the colored and blurred appearance of the peripheral part of the light-blocking members. Based upon this, the display quality of the color liquid crystal display device is markedly improved.
