Patent ID: 8358386

Claim:
A liquid crystal display device provided with a liquid crystal display panel, and a backlight disposed on a rear surface of the liquid crystal display panel, wherein the backlight is provided with a plurality of white light-emitting diodes arranged in a plane opposing the liquid crystal display panel, based on a chromaticity coordinate value representing a color of emission identified for each of the white light-emitting diodes, the white light-emitting diodes are selectively combined for arrangement in proximity in such a manner that a color of emission as a result of averaging over the white light-emitting diodes to be arranged in proximity takes a predetermined value of chromaticity coordinates, and based on the chromaticity coordinate value representing the color of emission identified for each of the white light-emitting diodes, the white light-emitting diodes are classified into at least three groups depending on whether the coordinate values are close to each other or not, the white light-emitting diodes respectively selected specifically from the at least three groups are placed in proximity as a combined unit, and by repeating such a unit placement, the white light-emitting diodes are arranged in the plane.
