Claim 10:
11. A display device comprising:
a substrate;
a display panel including a first display region having first pixels, a second display region having second pixels, and a third display region located between the first and second display regions and having third pixels; and
a light sensor disposed between the substrate and the display panel and which overlaps the second display region and does not overlap the first and third display regions in a plan view,
wherein the third display region does not have any light sensors, and
wherein transmissivity of the second display region is higher than transmissivity of the first display region,
