Abstract: A display device includes a base layer. A circuit layer is disposed on the base layer and includes at least one insulating layer and at least one transistor. An element layer is disposed on the circuit layer and includes a light emitting element and a light sensing element. The circuit layer includes a data line connected to the light emitting element and a readout line connected to the light sensing element. The readout line outputs a sensing signal in a sensing section of the display device. The readout line receives a reference voltage in a non-sensing section of the display device.
