Provided are an organic electric element, a display panel and a display device having high efficiency or long life by including layers having excellent hole transport ability and carrier resistance.

Organic electric element, display panel comprising the same and display device comprising the same

An organic light-emitting display (OLED) device includes an anode, an organic emitting layer on the anode, and a cathode on the organic emitting layer. The cathode is configured to transmit at least a part of light emitted from the organic emitting layer and is formed of an alloy having a first metal and an oxide of a second metal. The cathode contains an alloy of a metal and a metal oxide and has an increased thickness, such that the process margin for the cathode can be improved.

Organic light-emitting display device

An organic light-emitting display (OLED) apparatus includes an organic light-emitting device including an anode, an organic light-emitting layer, and a cathode. The OLED apparatus also includes an encapsulation element covering the organic light-emitting device, and a particular layer disposed between the organic light-emitting device and the encapsulation element. The particular layer is doped with a light absorption material that absorbs light having a wavelength shorter than a wavelength of light emitted from the organic light-emitting device so that variation in characteristics of the organic light-emitting device by external light is reduced. Accordingly, the lifespan of the OLED apparatus can be improved.

Organic light-emitting display apparatus

Embodiments disclosed herein relate to a light emitting display device comprising a plurality of subpixels, the plurality of subpixels including at least a first subpixel and a second subpixel. The light emitting display device includes a common layer shared by a first light emitting diode of the first subpixel and a second light emitting diode of the second subpixel, the common layer disposed between a first anode electrode and a first cathode electrode of the first subpixel and between a second anode electrode and a second cathode electrode of the second subpixel, and an auxiliary electrode disposed on a different layer from the common layer, the first anode electrode, the first cathode electrode, the second anode electrode, and the second cathode electrode, the auxiliary electrode connected to the common layer through a contact hole.
