Abstract:
An organic light-emitting device including a first electrode, a hole transport region on the first electrode, a light-emitting layer on the hole transport region, an electron transport region on the light-emitting layer, and a second electrode on the electron transport region. The electron transport region includes a first mixed electron transport layer and a second mixed electron transport layer on the first mixed electron transport layer. The first mixed electron transport layer includes a first electron transport compound and a second electron transport compound different from the first electron transport compound. The second mixed electron transport layer includes the first electron transport compound and a third electron transport compound different from the first electron transport compound and the second electron transport compound.
Abstract:
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.
