Abstract
An organic light emitting diode (OLED) display with improved long range uniformity, driving method and manufacturing method are disclosed. The OLED display manufacturing method includes forming a first active pattern on a substrate, a gate insulating layer, a gate electrode overlapping at least a part of the first active pattern on the gate insulating layer and an interlayer insulating layer. The OLED display manufacturing method further includes forming a conductive layer pattern and an anode of an OLED, forming a pixel defining layer and forming the OLED by forming an organic emission layer and a cathode. The conductive layer pattern is formed to cover the gate electrode and contact a first power line on the interlayer insulating layer.
