Patent ID: 8058795

Claim:
A display device in which pixels, each including an emission area, are arranged in a form of a matrix, said display device comprising: a first electrode formed from the emission area of said pixels to a non-emission area on a periphery of said emission area; a second electrode including a first conductive layer in said emission area and said non-emission area; and a second conductive layer in said non-emission area, wherein said first conductive layer is disposed on said second conductive layer in said non-emission area; a light emitting material layer formed between said first electrode and said second electrode in both said emission area and said non-emission area, wherein said first conductive layer is disposed on said light emitting material layer in said emission area and wherein said second conductive layer is disposed on said light emitting material layer in said non-emission area; a driving transistor, and a switching transistor, wherein a film thickness in said non-emission area of at least one of said first electrode and said second electrode is larger than film thickness in said emission area and said first electrode is connected to said driving transistor in said non-emission area.
