Abstract:
Disclosed is a color liquid display (LCD) employing a transmissive color liquid display panel. The display includes a complementary color light emitting diode, which is one of a cyan light emitting diode (21C), emitting cyan light, a yellow light emitting diode, emitting yellow light, and a magenta light emitting diode, emitting magenta light, in addition to light emitting diodes emitting three prime colors, as a light source. The display also includes a complementary color filter, having at least one of a cyan filter CFC having a transmission wavelength range corresponding to the cyan light, a yellow filter CFY having a transmission wavelength range corresponding to the yellow light and a magenta filter CFM having a transmission wavelength range corresponding to the magenta light, in addition to a tristimulus color filer, as a color filter (19).
