Abstract
An organic light emitting diode display with enhanced luminance and light uniformity is presented, along with a method of manufacturing the display. The display including: a substrate, a first signal line formed on the substrate and a second signal line extending perpendicularly to the first signal line, and thin film transistors formed on the substrate and electrically coupled to the first signal line and the second signal line. A planarization member is formed on the same layer as the first signal line and/or the second signal line, such that it does not overlap the first signal line, the second signal line, and the thin film transistors. An insulating layer is formed on the first signal line, the second signal line, the thin film transistors, and the planarization member. Two electrodes are formed on the insulating layer connected to one of the thin film transistors and sandwiching a light emitting member.
