The occurrence of the halo phenomenon caused in a display panel unit is detected in a liquid crystal display device that displays an image in the display panel unit including color filters of a plurality of colors by respectively controlling emission ratios of a plurality of LEDs emitting lights of colors respectively corresponding to the plurality of color filters. Upon detection, a part of the display panel unit, for example, the channel number and the vicinity thereof are set as a non-detection area in which the detection of the halo phenomenon is restricted and the remaining area is set as a detection area. The chroma of light, which corresponds to mixed light from the plurality of LEDs, is reduced by controlling the emission ratios of the LEDs on the basis of the detection result in the detection area, so that the color of light is closer to white. |
