Abstract: A display apparatus is disclosed that includes a substrate, a partition wall, and wiring. The substrate includes a display area and a peripheral area. The partition wall is arranged in the peripheral area. The wiring is arranged over the substrate extends from the display area to the peripheral area, and inserted into the partition wall or passes through the partition wall. The wiring includes at least one through hole.

Abstract: A display device includes a substrate including a first pixel area, a second pixel area spaced apart from the first pixel area, and a valley area between the first pixel area and the second pixel area, a first insulating layer on the substrate and in both the first pixel area and the second pixel area, a penetration hole through the first insulating layer and corresponding to the valley area, the penetration hole exposing a side surface of the first insulating layer and an upper surface of the substrate to outside the first insulating layer, a crack prevention pattern which is in the penetration hole and covers the side surface of the first insulating layer, and a second insulating layer facing the first insulating layer with the crack prevention pattern therebetween, the second insulating layer in contact with the upper surface of the substrate at the penetration hole.

Abstract: Provided is a display device having defined therein an opening corresponding to a boundary region, and including a plurality of insulating layers disposed on a base layer, an organic layer disposed in the opening, a first connection electrode disposed on the uppermost insulating layer among the plurality of insulating layers, connected to a first signal line through a first contact hole passing through the organic layer, and connected to a transistor through a second contact hole passing through corresponding insulating layers among the plurality of insulating layers, and a second signal line disposed on a layer different from a layer on which the first line is disposed.
