<p>An image display device with a partial ignition operable lighting unit is provided for making it possible to improve image quality by the reduction of uneven brightness or uneven chromaticity. Illumination light (Lout) from a lighting unit (10), which ignites in a unit of a partial ignition operable light unit (4), is used for the display of an image on a liquid crystal display panel (2) in accordance with a video signal. The illumination light (Lout) from the lighting unit (10), which ignites in a unit of the partial ignition operable light unit (4), is received by a plurality of illumination light sensors (13) in the lighting unit (10) and, based on the received light data (D1), a light emitting amount of each partial ignition operable light unit (4) is controlled. Further, the disposition of the illumination light sensors (13) is arranged for not less than two illumination light sensors (13) to receive the light (Lout) from one partial ignition operable light unit (4). According to the present invention, the reliability of a value of the received light data (D1) by the illumination light sensor (13) can be improved. With this, even if the receiving characteristics are uneven between the illumination light sensors (13), uneven light emitting characteristics, if any, can be reduced between the partial ignition operable light units (4).</p> |
