Abstract: A display apparatus includes a semiconductor layer disposed on a substrate and including a channel area, a source area and a drain area that are disposed at both sides of the channel area, and a first opening portion disposed adjacent to the source area or the drain area, and a first electrode overlapping and electrically connected to the source area or the drain area and including an edge adjacent to the first opening portion. The edge of the first electrode is concave in a direction from the first opening portion toward the source area or the drain area.

Abstract: A display apparatus includes a flexible substrate, a thin-film transistor unit, and a light-emitting unit. The flexible substrate includes a display area has a first area, a peripheral area which is adjacent to the display area, and a first penetrating portion corresponding to the first area. The thin-film transistor unit is in the display area and at least a portion of the peripheral area. The thin-film transistor unit includes a thin-film transistor and an insulation layer and has a second penetrating portion at a location corresponding to the first penetrating portion. The light-emitting unit is on the thin-film transistor unit and includes a pixel electrode, an intermediate layer including an emission layer, and a counter electrode.
