Patent ID: 7439671

Claim:
An organic electroluminescent panel comprising: a substrate; a pair of electrodes positioned relative to the substrate; and at least one of an organic electroluminescent element including at least one of an organic layer having an emission layer disposed between the pair of electrodes; wherein a surface-emitting element due to luminescent areas of the organic electroluminescent element is formed on the substrate, and plural organic electroluminescent elements are arranged to form a display region, wherein one film formation region is related to the organic electroluminescent element which is made of an uniform film forming material is formed in accordance with one opening of the film forming mask, and wherein the one film formation region is formed by plural layers which are formed respectively at each setting of the film forming mask, and wherein the emission layer is formed by plural layers of a first emission layer and a second emission layer, and the second emission layer is formed on the first emission layer, and wherein the second emission layer is formed by same material as the first emission layer.
