  • Organic light emitting diode display and manufacturing method thereof
    Patent number: 9666658
    Abstract: Disclosed is an organic light emitting diode (OLED) display including an organic light emitting diode (OLED) display including an insulation substrate and a first electrode disposed on the insulation substrate. A pixel defining layer surrounds the first electrode. The pixel defining layer forms a pixel area on the first electrode. An organic emission layer is disposed on the first electrode in the pixel area. An electrode connecting portion is disposed on the pixel defining layer. A second electrode is disposed on the organic emission layer. The second electrode is connected to the electrode connecting portion.
    Type: Grant
