Abstract: A display device including a display area and a non-display area, an inorganic insulating layer disposed on a substrate, the inorganic insulating layer disposed in the display area and the non-display area, pixels disposed on the substrate and overlapping the inorganic insulating layer in a plan view, the pixels disposed in the display area, and an organic insulating layer disposed on the substrate and overlapping the inorganic insulating layer and the pixels in a plan view, the organic insulating layer disposed at least in the display area. The non-display area includes an organic layer-free area including at least one of a corner and an outer edge area of the display device. The organic insulating layer is disposed on a portion of the substrate so as to be disposed in an area except for the organic layer-free area.

Abstract: A display apparatus includes a display panel, a data driver and a gate driving circuit. The display panel includes pixels, data lines, and gate lines. The data driver applies data voltages to the data lines. The data driver includes dummy stages. The gate driving circuit applies gate signals to the gate lines, and is disposed between opening portions in a display area of the display panel. The gate driving circuit includes normal stages that output the gate signals to the gate lines. The dummy stages output a reset signal to at least one of the normal stages.

Abstract: A tiled display device includes a first display device and a second display device, each of the first display and the second display including a display area and a non-display area. The first display device and the second display device are bonded to each other. The first display device includes an alignment key area and a lower electrode layer. The alignment key area performs an alignment key function when a process is performed on the tiled display device. The lower electrode layer includes a first lower electrode layer and a second lower electrode layer. The first lower electrode layer surrounds the display area of the first display device and the second lower electrode layer is disposed in the alignment key area.
