Abstract: A display device includes a main display area and a sub-display area adjacent to each other, a transistor in the main display area, a light emitting element which is in the sub-display area and electrically connected to the transistor, the light emitting element including a first electrode, a light emitting layer and a second electrode, a connection line which extends from the main display area to the sub-display area and connects the transistor to the light emitting element, and a via layer between the transistor and the light emitting element. The via layer has a first thickness overlapping the first electrode together with having a second thickness which overlaps the connection line and is smaller than the first thickness.

Abstract: A display device includes a display area and a pad area. Pixel electrodes are disposed in the display area. An inorganic insulating layer is disposed in the display area and partially on the pixel electrode. A bank structure is disposed on the inorganic insulating layer. A pad structure is disposed in the pad area and is electrically connected to a fan-out line disposed in the pad area and the display area. Light emitting layers are disposed on the pixel electrodes and in openings of the bank structure. Common electrodes are disposed on the light emitting layers and in the openings of the bank structure. The bank structure includes multiple first bank layers including different metal materials. One of the bank layers and the pad layer includes a tip protruding from a sidewall thereof.
