Abstract: PROBLEM TO BE SOLVED: To allow quick and accurate correction of image sticking.
SOLUTION: A display device comprises an EL panel 2, a plurality of light receiving sensors 3, and a control part. The control part corrects the reduction of brightness due to aging degradation on the basis of emission brightness of respective pixels of the EL panel 2 measured by the light receiving sensors 3. The light receiving sensors 3 are bonded to a support substrate 71 on a rear side of the EL panel 2 by an adhesive layer 141 having a refractive index lower than that of the support substrate 71. Thus, light emitted from an organic EL layer 79 and reflected by a counter substrate 72 goes straight and impinges on the light receiving sensors 3, as shown by an optical path Xd. That is, the light receiving sensors 3 can receive light which enter at a horizontally near angle, out of light from pixels 101 which is far away from the light receiving sensors 3. This invention is applicable to, for example, a panel using self-light emission elements.
