Beschreibung
Zusammenfassung:	The present invention relates to a display device that measures display characteristics (such as luminance or chromaticity) associated with a display panel. The display device of the present invention has a light sensor (5) provided at a position allowing outgoing light from a screen (1a) of a liquid crystal panel (1), which serves as the display panel, and extraneous light reflected on the screen (1a) to enter the light sensor (5). Since the light sensor (5) is provided at the position, it is possible to measure the characteristics of the display panel and also the characteristics of the extraneous ambient light reflected on the screen. Thus, it is possible to accurately adjust the display characteristics based on the measurement results.
