Abstract
Official abstract text for this publication.
A display device includes a pixel which includes a first photosensor portion having a first photodiode for detecting visible light, which is provided together with a display element portion; and a pixel which includes a second photosensor portion having a second photodiode for detecting infrared rays, which is provided together with another display element portion. The second photosensor portion detects infrared rays included in external light, and selects an imaging element and adjusts sensitivity in accordance with the amount of infrared rays detected by the second photosensor portion.
