Abstract
The present invention discloses a transflective mode color liquid crystal display, whose white backlight source is composed of several narrowband monochromatic light sources. A color filter for displaying colors is designed to match the wavelength of each of the monochromatic light sources so that the color filter can let a monochromatic light source of one color be transmitted, while selectively absorb the wavelengths of the monochromatic light sources of other colors. The present invention can achieve high color saturation at the backlight mode while maintaining high reflectance.
