A display device includes a base layer including first and second emission regions, first and second electrodes, a first organic layer in the first emission region, and a second organic layer in the second emission region. The first organic layer includes a first electron transport layer, a first auxiliary layer on the first electron transport layer, a first emission layer on the first auxiliary layer, a second auxiliary layer on the first emission layer, and a first hole transport layer on the second auxiliary layer. The second organic layer includes a second electron transport layer, a third auxiliary layer on the second electron transport layer, a second emission layer on the third auxiliary layer, a fourth auxiliary layer on the second emission layer, and a second hole transport layer on the fourth auxiliary layer.

Display device with emission region having multiple emission layers

A method of fabricating an organic light emitting device includes forming a first electrode layer on a substrate, surface-treating the first electrode layer with CFplasma, forming a first common layer containing pentacene on the surface-treated first electrode layer, forming an organic light emitting layer on the first common layer, forming a second common layer on the organic light emitting layer, and forming a second electrode layer on the second common layer. The CFplasma treatment enhances the luminous efficiency of the organic light emitting device.
