Abstract: A display device can include a first sub light-emitting element, a second sub light-emitting element and a third sub light-emitting element. The first sub light-emitting element includes a 1-1 hole transport layer, a 1-2 hole transport layer disposed on the 1-1 hole transport layer, and a first organic light-emitting layer disposed on the 1-2 hole transport layer. The second sub light-emitting element includes a 2-1 hole transport layer, a 2-2 hole transport layer disposed on the 2-1 hole transport layer, and a second organic light-emitting layer disposed on the 2-2 hole transport layer. The third sub light-emitting element includes a 3-1 hole transport layer, a 3-2 hole transport layer disposed on the 3-1 hole transport layer, and a third organic light-emitting layer disposed on the 3-2 hole transport layer.

Abstract: A display device can include a display panel having a first display area in which first pixels are disposed, and a second display area in which second pixels and a light-transmission area disposed between the second pixels are disposed, and a sensor disposed to correspond to the second display area. One of the second pixels includes sub-pixels. The display panel can include a circuit layer, a light emitting element layer disposed on the circuit layer, and an anti-reflection layer disposed between a planarization layer of the circuit layer and an anode electrode of the light emitting element layer. Further, a space is formed between an anode electrode of one sub-pixel and an anode electrode of another adjacent sub-pixel, and a path of light directed to the sensor through the space is changed by the anti-reflection layer. Accordingly, the display device can minimize the amount of light reaching the sensor.

Abstract: A display device includes a substrate including a plurality of sub pixels. The device includes a transistor disposed above the substrate. The device includes a planarization layer which is disposed above the transistor and has a first open area. The device includes an anode electrode which is disposed in the first open area and a side portion of the planarization layer adjacent to the first open area. The device includes a bank which covers a part of the anode electrode and has a second open area corresponding to the first open area. The device includes an organic layer which is disposed on the anode electrode exposed by the second open area. The device includes a cathode electrode disposed on the organic layer, and a side portion of the planarization layer has a bumpy shape and an end of the anode electrode has a bumpy shape from a plan view.
