An organic light emitting device includes a first light-emitting layer between an anode and a cathode, the first light-emitting layer including a first light-emitting part and a second light-emitting part, a second light-emitting layer spaced apart from the first light-emitting layer and including a third light-emitting part and a fourth light-emitting part, the third light-emitting part overlapping the first light-emitting part and not overlapping the second light-emitting part, and the fourth light-emitting part not overlapping either of the first light-emitting part and the second light-emitting part, an intermediate layer between the first light-emitting layer and the second light-emitting layer, a hole transport region to inject/transport a hole into the first light-emitting part, the second light-emitting part, and the fourth light-emitting part, and an electron transport region to inject/transport an electron into the second light-emitting part, the third light-emitting part, and the fourth light-emitting part.

Organic light emitting device

A method of manufacturing a display device, the method including providing a first electrode on a base substrate; providing a fluorine-containing pixel defining layer on the base substrate and the first electrode such that the pixel defining layer exposes at least a portion of the first electrode; pretreating the first electrode; and providing an organic layer on the first electrode after pretreating the first electrode, wherein pretreating the first electrode includes performing a first treatment operation of treating an exposed surface of the first electrode using a first plasma gas; and performing a second treatment operation after performing the first treatment operation, the second treatment operation including treating the exposed surface of the first electrode using a second plasma gas, wherein the second plasma gas is different from the first plasma gas and includes hydrogen.

Method of manufacturing display device including a surface treatment operation to remove activated fluorine

An organic light-emitting diode (OLED) display and a method of manufacturing the same are disclosed. In one aspect, the OLED display includes a substrate, a plurality of pixel electrodes formed on the substrate and separated from each other. The OLED display also includes an opposite electrode formed as one body and corresponding to the pixel electrodes, wherein the thickness of the opposite electrode varies depending on a position. The OLED display further includes an intermediate layer formed between the pixel electrodes and the opposite electrode, wherein the intermediate layer includes at least an emission layer.
