ORGANIC LIGHT EMITTING DEVICE AND FABRICATING METHOD THEREOF

摘要

A fabricating method of an organic light emitting device is provided. First to fourth lower pixel electrodes are respectively formed in first to fourth pixel regions of a substrate. By ink-jet printing processes, an interlayer is formed on the first to fourth lower pixel electrodes, and first to third color patterns are respectively formed on the interlayer in the first to third pixel regions. A fourth color layer is formed to cover the first to third color patterns and the interlayer in the fourth pixel region. Colors of the first to third color patterns and the fourth color layer are different. An upper pixel electrode is formed on the fourth color layer. A color filter arranging over the upper pixel electrode filters out a first color light, a second color light, light of third and fourth colors, and the fourth color light corresponding to the first to fourth pixel regions.
