Document Type and Number:
WIPO Patent Application WO/2013/084577
Kind Code:
A1
Abstract:
In a liquid crystal display device (1) according to one embodiment of the present invention, a solid-state light emitting element is provided with: a first light emitting element that emits short wavelength light having a wavelength within the range from 360 nm to 420 nm; and a second light emitting element that emits visible light. A plurality of electrodes of the liquid crystal display device (1) include: light guide electrodes (3c, 3d) which drive liquid crystals contained in a liquid crystal layer (6) for the emission of short wavelength light; and pixel electrodes (3a, 3b) which drive liquid crystals contained in the liquid crystal layer (6) for the emission of visible light. A plurality of light receiving elements include a first light receiving element that overlaps a blue filter (14B) when viewed in plan and a second light receiving element that overlaps a green filter (14G), a red filter (14R) or a black matrix (BM) when viewed in plan, said light receiving elements being phototransistors, each of which comprises a transparent channel layer that contains oxides of two or more metals selected from among gallium, indium, zinc, hafnium, tin and yttrium.
