<P>PROBLEM TO BE SOLVED: To provide a display unit which is provided with a sensitivity correction function and a light intensity detection device that can be manufactured in a simple process. <P>SOLUTION: The display unit has a display area and first and second photodetectors 10a and 10b on a substrate and outputs, as a light intensity signal S, a light intensity detected by the first and second photodetectors 10a and 10b. The first photodetector 10a includes a first photodetection circuit LS1 outputting a first output signal Sa to a photosensor reader 20, and a light-reducing unit. The second photodetector 10b includes a second photodetection circuit LS2 outputting a second output signal Sb to a photosensor reader 20. The photosensor reader 20 includes a photodegradation factor calculator 21 calculating a photodegradation reparation factor K, a photodegradation rate calculator 22 deriving a photodegradation rate D based on the photodegradation reparation factor K, and a light signal output unit 24 outputting a light intensity signal S based on the photodegradation rate D. <P>COPYRIGHT: (C)2009,JPO&INPIT |
