A display apparatus includes a sensor layer including sensors; a pixel layer disposed on the sensor layer and including pixel areas and pixels in the pixel areas; and an opaque layer disposed between the sensor layer and the pixel layer and having holes corresponding to light-transmitting areas of pixel areas in which pixels that emit light of a specific color are disposed.

Display apparatus

A pixel of an organic light emitting diode display device includes a switching transistor which transfers a data voltage in response to a scan voltage applied thereto through a scan line, a storage capacitor which stores the data voltage transferred by the switching transistor, a driving transistor which generates a driving current based on the data voltage stored in the storage capacitor, an organic light emitting diode which emits light based on the driving current, and an anode discharging capacitor connected between the scan line and an anode of the organic light emitting diode.
