Abstract:
1. A liquid crystal color display comprising a color filter having plural pixels of 3 colors of red, green, and blue, plural light shutters which controls a transmitting light quantity of each pixel by opening and closing a liquid crystal, and a light source which is a 3 band tube, wherein an average of normalized emitting spectrum of light source (brightness when maximum value is 1), in range of λ±3 nm when a wavelength of the maximum green pixel transmittance of a color filter is λ, is in a range of 0.1 to 0.373 and a wavelength of a coinciding point of transmittance of blue pixel whose wavelength is longer than the peak wavelength of the transmitting wavelength band of blue pixel of a color filter, and transmittance of green pixel whose wavelength is shorter than the peak wavelength of the transmitting wavelength band of green pixel of a color filter, is 500 nm or shorter.
