Abstract: A display device includes first, second, and third sub-pixels arranged in a first direction and including a pixel circuit. A photo-sensing pixel includes a sensor circuit. A first data line connected to the first sub-pixel extends in a second direction. A second data line connects to the second sub-pixel and extends in the second direction. A third data line connects to the third sub-pixel and extends in the second direction. A readout line connected to the photo-sensing pixel extends in the second direction. A first additional line connects to the photo-sensing pixel and extends in the second direction and receives a reset voltage. The first additional line is disposed in the same layer as the first, second, and third data lines. The readout line is disposed on a different layer from the first, second, and third data lines, and the first additional line.
