Abstract
An image display device includes a liquid crystal panel section, a light source section divided into a plurality of regions, a light detection section detecting the light intensity of the light source section, and a timing generation section. The timing generation section generates a light emission drive signal which turns on each of the regions of the light source section according to scanning in the liquid crystal panel section, and which turns on all the regions of the light source section in a light detection period, and generates a light detection gate signal allowing the detection of the light detection section to be effective in the light detection period.
