Abstract
A display device may include: a first substrate including pixel areas; a circuit element layer disposed on a first surface of the first substrate, and including at least one conductive layer; a light emitting element layer disposed on the circuit element layer; pixels each including a circuit element and a light emitting element disposed on the circuit element layer and the light emitting element layer in a corresponding one of the pixel areas; a first light transmitting hole array layer including first light transmitting holes distributed in the circuit element layer; and a photo sensor array layer disposed on a second surface of the first substrate and configured to overlap with the first light transmitting hole array layer, the photo sensor array layer comprising photo sensors. The first light transmitting holes may include openings distributed in the at least one conductive layer.
