An organic light emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes a flexible substrate and a plurality of OLEDs. The flexibility substrate includes at least one curved portion. The OLEDs are positioned in every pixel area that is set on the flexible substrate and includes a pixel electrode, an organic emission layer, and a common electrode. At least one OLED that is positioned at a curved portion in the OLEDs is formed in a lens shape and concentrates light toward the center of a pixel area.
