Abstract: A display device includes a substrate including a display region, a hole, and a hole edge region surrounding the hole, first data lines disposed on the substrate, extending in a first direction, arranged in a second direction intersecting the first direction in the display region, and bypassing the hole along the hole edge region, and second data lines disposed on the substrate, extending in the first direction, alternately arranged with the first data lines in the second direction in the display region, and bypassing the hole along the hole edge region. At least one of the first data lines intersects at least one of the second data lines such that the first data lines are disposed adjacent to each other and the second data lines are disposed adjacent to each other in the hole edge region.

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.
