Patent ID: 7795800

Claim:
An organic electro luminescence device, comprising: a display area and a dummy area, the display area having a plurality of display pixels for displaying an image, and the dummy area having a plurality of dummy pixels and being provided at a periphery of the display area; an anode integrally formed at two or more of the display pixels of the display area on a substrate, wherein the dummy area has no anode; a buffer layer on the anode of the display area and on the substrate of the dummy area, the buffer layer being formed between the display pixels in the display area; a barrier on the buffer layer in the display pixels of the display area and the dummy pixels of the dummy area for partitioning the display pixels and the dummy pixels on the substrate, wherein an upper surface of the barrier in the dummy pixels is lower than an upper surface of the barrier in the display pixels; an organic electro luminescence layer in the display and dummy pixels; and a cathode on the organic electro luminescence layer, wherein the dummy pixels have the same shape as the display pixels, and wherein the organic electro luminescence layer is partitioned by the barrier in the display area and the dummy area, wherein solvent molecules of the organic electro luminescence layer in the display pixels at an edge portion of the display area have substantially the same concentration as solvent molecules of the organic electro luminescence layer in the display pixels at the display area.
