Organic light emitting display device and method of manufacturing the same
Abstract:
Discussed is an organic light emitting display device. The organic light emitting display device includes a substrate in which red, green, and blue pixel areas are defined, a first electrode and a first hole transporting layer that are formed on the substrate, first to third emission common layers formed in each of the pixel areas on the first hole transporting layer, and an electron transporting layer and a second electrode that are formed on the third emission common layer. Accordingly, color mixture is prevented, limitations due to a defective mask are overcome, a process is simplified, and the manufacturing cost is saved.
