Abstract: A pixel capable of adjusting a threshold voltage of a driving transistor, the pixel including: a display element configured to emit light during an emission period and including an anode and a cathode, the first transistor including an upper gate and a lower gate and configured to control a magnitude of a driving current flowing to the display element, a storage capacitor connected to the upper gate of the first transistor, and a second transistor configured to be turned on during a data writing period to transmit a data voltage to the first transistor, wherein a lower gate-source voltage of the first transistor has a first voltage level in the data writing period and a second voltage level in the emission period.

Abstract: A display apparatus includes a substrate including a transmitting area, a display area surrounding the transmitting area, a first non-display area disposed between the transmitting area and the display area, and a second non-display area surrounding the display area. A plurality of pixels is arranged in the display area. A set of 2n connection wirings (where n is a positive integer) is disposed in the first non-display area and each of the 2n connection wirings extends along at least a part of an edge of the transmitting area. Each of a plurality of voltage wirings extends in a first direction and is connected to at least some of pixels disposed in a common row from among the plurality of pixels. Each of the plurality of voltage wirings is connected to one of the 2n connection wirings.
