Abstract:
A liquid crystal display device includes an array substrate, a liquid crystal layer, and a color filter substrate facing the array substrate through the liquid crystal layer. The color filter substrate includes a carbon light-shielding layer, an organic pigment light-shielding layer, and color filters formed such that the organic pigment light-shielding layer overlaps with at least one of the color filters in a direction perpendicular to a substrate plane. The array substrate includes a first light sensor that detects light which passes through any of the color filters without passing through the organic pigment light-shielding layer in the direction perpendicular to the substrate plane. The array substrate further includes a second light sensor that detects light which passes through the organic pigment light-shielding layer and any of the color filters in the direction perpendicular to the substrate plane.
