GRADATION VOLTAGE CORRECTION SYSTEM AND DISPLAY APPARATUS UTILIZING THE SAME

摘要

A gradation voltage correction system (14b) is provided in a liquid crystal display device (1) that is configured to be capable of displaying a color image, and corrects gradation voltages to be supplied to a plurality of pixels. The gradation voltage correction system (14b) includes a color sensor (chromaticity change acquiring portion) (13) for acquiring a change in chromaticity of illumination light from light-emitting diodes (4) and a correction determining portion (14c) for determining correction values of the gradation voltages for each color of the red, green, and blue pixels based on the detection (acquisition) results of the color sensor (13).
