Abstract: A display device includes: a substrate; a first conductive layer on the substrate and including a conductive pattern electrically connected to a first transistor; a first organic planarization layer on the first conductive layer; an organic layer on the first organic planarization layer and including a first bank having a first height and a second organic planarization layer having a second height lower than the first height; a first electrode on the organic layer; a second electrode on the organic layer and spaced apart from the first electrode; and a light-emitting element between the first electrode and the second electrode. The first organic planarization layer has a first opening exposing the conductive pattern, and the second organic planarization layer has a second opening exposing the conductive pattern. Sidewalls of the first opening and sidewalls of the second opening are not aligned in line with each other.

Abstract: A display device having a pad area and a display area is provided. The display device includes: a substrate; a pad structure on the substrate in the pad area; and a display element part on the substrate in the display area. The pad structure includes a first pad pattern, a second pad pattern on the first pad pattern, and a third pad pattern on the second pad pattern, and the display element part includes a light emitting element configured to emit light in a display direction. The second pad pattern has a first area and a second area, the second pad pattern and the third pad pattern do not contact each other in the first area, and the second pad pattern and the third pad pattern contact each other in the second area.
