Abstract: A display device includes: a display panel including a substrate having first and second opposing surfaces and a light emitting element disposed on the first surface of the substrate, the display panel having a transmission area through which light is transmitted from outside the display device; a sensor facing the surface of the substrate and configured to sense light received through the transmission area; and an anti-reflective member disposed between the sensor and the substrate and to transmit light such that reflection of applied light is reduced. The anti-reflective member overlaps the transmission area when viewed in a direction normal to the first and second surfaces of the substrate.
