DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/001661
Kind Code:
A1
Abstract:
A liquid crystal display device (10) has a function of imaging a subject to be imaged. The liquid crystal display device (10) is provided with a liquid crystal panel (11) which transmits entered light and can vary transmissivity of the light; a backlight (15) which radiates light ranging from visible light to non-visible light to the liquid crystal panel (11); and an optical sensor (2), which is arranged in the liquid crystal panel (11) and receives at least infrared light (non-visible light) that enters the liquid crystal panel (11). The ratio of the visible light radiated to the subject to the non-visible light is adjusted, and the subject is imaged by at least the non-visible light. Therefore, an imaging function and a display function are both provided and at least imaging by non-visible light is made possible.
