A liquid crystal display according to an embodiment includes a first light-emitting device that emits short-wavelength light of a wavelength 360 nm to 420 nm and a second light-emitting device that emits visible light. Electrodes of the liquid crystal display includes a light-guiding electrode that drives a liquid crystal contained in the liquid crystal layer to emit the short-wavelength light and a pixel electrode that drives the liquid crystal contained in the liquid crystal layer to emit the visible light. The photoreceptors are each a phototransistor including a transparent channel layer containing two metallic oxides or more from gallium, indium, zinc, hafnium, tin, and yttrium. The photoreceptors include a first photoreceptor overlaps with the blue filter in the plan view and a second photoreceptor overlaps with the green filter, the red filter, or the black matrix in the plan view.

Liquid crystal display

A color filter substrate for use in a fringe-field switching mode liquid crystal display wherein the color filter substrate and an array substrate provided with a comb-shaped pixel electrode having an electrode width of 10 &#x3bc;m or less are arranged facing each other with a liquid crystal layer interposed therebetween. The color filter substrate comprises a transparent substrate, a black matrix provided on the transparent substrate, includes an organic pigment as a main coloring agent, color pixels having a relative dielectric constant of 2.9 or more but 4.4 or less, and a transparent resin layer provided on the color pixels. The relative dielectric constant of each of the color pixels falls within &#xb1;0.3 of an average relative dielectric constant of the color pixels.
