Abstract
In order to simultaneously carry out, at a smaller sensor density, (i) detection of color information (recognition of a color) of visible light which enters a detection target surface and (ii) detection of an input position of the visible light, a liquid-crystal panel () included in a liquid-crystal display device of the present invention has an area sensor function of detecting color information and an input position of visible light by sensing an input image of the visible light on a panel surface. The liquid-crystal panel () (position detecting section) includes (i) a yellow sensor (Y) including a light sensor element () which senses an intensity of green light and red light from among three primary color lights and (ii) a cyan sensor (C) including a light sensor element () which senses an intensity of blue light and green light from among the three primary color lights. Sensing of the input image of the visible light on the panel surface by each of the yellow sensor (Y) and the cyan sensor (C) allows detection of the color information and the input position.
