Abstract: An organic light emitting diode display is disclosed in which a flow control pattern of an organic protective layer is disposed to implement a thin bezel. In an active area and a bezel area defined on a substrate, the flow control pattern disposed reduces the flow of a protective layer so as to minimize area size of the bezel area.
