Abstract: A display device includes a display area including pixels and a non-display area adjacent to the display area. A circuit layer is disposed on the display area and the non-display area. A light emitting layer is disposed in the display area and includes a light emitting element defining the pixels. A transmitter is disposed on the circuit layer in the non-display area and transmits a sensing signal. A receiver is disposed in the display area separated from the transmitter and receives the sensing signal. A pixel control circuit for controlling the light emitting element is disposed in the circuit layer in the display area. A driving control circuit is disposed in the circuit layer in the non-display area. The driving control circuit is electrically connected to the transmitter.
