Organic light emitting display and method for fabricating the same

摘要

Discussed are an organic light emitting display and a method for fabricating the same to improve color purity and efficiency. The organic light emitting display includes a substrate having first to third sub-pixels, first and second electrodes formed on the substrate, the first and second electrodes facing each other, a red light emitting layer formed in the first sub-pixel between the first and second electrodes, a green light emitting layer formed in the second sub-pixel between the first and second electrodes, and a blue common light emitting layer formed in the first to third sub-pixels between the first and second electrodes, wherein a thin film layer formed between the first electrode and the blue common light emitting layer and contacting the blue common light emitting layer includes a blue host.
