Abstract: 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.
