Abstract:
1. A liquid crystal display device comprising: a light source; a back light controlling a luminous intensity distribution from said light source; and a liquid crystal display comprising liquid crystal display panel, wherein said liquid crystal display panel is provided in a light emitting side of said back light and controls a transmission rate from said back light, wherein a maximum intensity of a light emitting spectrum of said back light is in a range of 510 nm to 530 nm in a wavelength range of 500 nm to 550 nm, wherein said liquid crystal panel comprises a red color filter, which transmits red components, a green color filter, which transmits green components and a blue color filter, which transmits blue components, and a transmit spectrum of said green color filter comprises a half value of a maximum transmitting rate of 500 nm to 590 nm in a wavelength range, and wherein the liquid crystal display device has a color reappearance area between 96% to 117% and a change of white chromaticity between 0.012 to 0.035 at a viewing angle of 60°.
