ABSTRACT:
A color liquid crystal display includes a wavelength converter having a plurality of wavelength conversion areas and a plurality of transparent areas. The wavelength conversion areas are disposed at the positions corresponding to red and green filters while the transparent areas are disposed at the positions corresponding to blue filters. After passing through the wavelength conversion areas, a blue light is converted to a broadband yellow light. The broadband yellow light will be subsequently converted to a red or green light of interest when it passes through red or green filters. The blue light will experience no change in wavelength when it passes through the transparent areas. With such arrangement, the displayed brightness and saturation of red and green colors can be improved, and the displayed brightness and saturation of blue color can also be enhanced.
