Abstract
A liquid crystal display (LCD) includes a dielectric multilayer formed inside an LCD cell and a light source behind the LCD cell wherein an image is generated by the LCD in accordance with input video signals when either ambient light is incident on the surface of the dielectric multilayer or when light is generated by the light source. The LCD cell has a first substrate and a second substrate being located facing each other with a liquid crystal layer therebetween. The dielectric multilayer includes multiple layers of transparent dielectric materials with different refractive index. In the LCD of the present invention, since the dielectric multilayer is formed inside the LCD cell, the light only passes through one of the substrates in the reflective mode thereby increasing efficiency while meeting the need for low power consumption.
