Provided are an image display device and an image display method capable of reducing a fear of degradation of the original image quality caused by excessively suppressing uneven luminance or uneven color. 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 (30) which is displayed as an OSD image and the vicinity (30A) thereof are set as a non-detection area in which the detection of the occurrence 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 and to be made incident upon the color filters, 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. |
