Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid crystal display device in which a frame area where a photo sensor is disposed can be made smaller.SOLUTION: The liquid crystal display device includes a light guide plate for converting light from a light source to a planar backlight and radiates it, a first frame for storing the light guide plate, a liquid crystal display panel arranged at a radiated side of the backlight, and a photosensor that is arranged facing a side face of the light guide plate and detects a light volume of the backlight. The photosensor is arranged while facing the side wall of the light guide plate through a hole or a cutout formed in the side wall of the first frame.
