ABSTRACT:
The present invention provides a liquid crystal display capable of detecting external light by an optical sensor without providing a window in front of a product. A top face of a liquid crystal display panel (18) corresponds to a display surface. A light-guiding plate (19) is disposed on a rear face of the liquid crystal display panel (18). A backlight (9) shown in FIG.1is attached to the light-guiding plate (19). Light emitted from the backlight (9) is guided to the display surface of the liquid crystal display panel (18) by the light-guiding plate (19). A reflection sheet (20) is disposed on a bottom face of the light-guiding plate (19). An optical sensor (10) is attached to a side face of the light-guiding plate (19) with its light-receiving face facing the inside of the light-guiding plate (19).
