Patent attributes
Disclosed are an organic light emitting display device and a method of manufacturing the same. The organic light emitting display device includes a thin film transistor (TFT) including a gate electrode and a source electrode provided on a substrate, a planarization layer provided on the TFT to have a step height, an anode electrode provided on the planarization layer and connected to the source electrode, an organic light emitting layer provided on an upper surface of the anode electrode, and a cathode electrode provided on the organic light emitting layer. The planarization layer includes a first area and a second area, provided at different heights, and a third area including an inclined surface between the first area and the second area. Also, the method includes forming a planarization layer on the source electrode to have a step height. The forming of the planarization layer includes forming the planarization layer including a first area and a second area, provided at different heights, and a third area including an inclined surface between the first area and the second area. Accordingly, the anode electrode provided on the inclined surface of the third area reflects light which is emitted from the organic light emitting layer and moves to a side surface of the organic light emitting layer, thereby enhancing emission efficiency.
