A liquid crystal display 1 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. A plurality of electrodes of the liquid crystal display 1 includes a light-guiding electrode 3c, 3d that drives a liquid crystal contained in the liquid crystal layer 6 to emit the short-wavelength light and a pixel electrode 3a, 3b that drives the liquid crystal contained in the liquid crystal layer to emit the visible light. The plurality of photoreceptors are each a phototransistor including a transparent channel layer containing two metallic oxides or more from gallium, indium, zinc, hafnium, tin, and yttrium, wherein the plurality of photoreceptors include a first photoreceptor overlaps with the blue filter 14B in the plan view and a second photoreceptor overlaps with the green filter 14G, the red filter 14R, or the black matrix BM in the plan view. |
