Abstract: A display device includes first light emitting elements and first pixel circuits in a first display area and connected to each other, second pixel circuits in a third display area and connected to second light emitting elements in a second display area, a first initialization voltage supply line to provide a first initialization voltage to the first pixel circuits, a second initialization voltage supply line to provide a second initialization voltage to the second pixel circuits, and a connection line-pattern unit including horizontal connection lines extending in a row direction and vertical connection lines extending in a column direction. A first vertical connection line of the connection line-pattern unit is connected to the pad unit. A second horizontal connection line of the connection line-pattern unit is to connect the second pixel circuits to the second initialization voltage supply line.

Abstract: A display apparatus including a first display area, a second display area including a transmissive area, and a peripheral area outside the first display area and the second display area. The display apparatus includes a substrate, a first pixel circuit on the substrate and in the first display area, and an organic insulating layer on the first pixel circuit and covering the first display area and the second display area. A thickness of the organic insulating layer in the second display area is less than a thickness of the organic insulating layer in the first display area.

Abstract: A thin-film transistor array substrate includes a substrate, a thin-film transistor disposed on the substrate, where the thin-film transistor includes a semiconductor layer including a channel area and a gate electrode overlapping the channel area, and a storage capacitor including a lower electrode disposed on the channel area and an upper electrode disposed to overlap the lower electrode, where an opening having a single closed curve-shape is defined through the upper electrode. On a plane, the upper electrode includes a first recessed portion and a second recessed portion, each exposing an edge of the lower electrode.
