Abstract: 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.

Abstract: 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.
