Abstract: An organic light emitting display (OLED) device, and a method of manufacturing the OLED device are discussed. The OLED device according to one embodiment includes a substrate; a first pixel electrode, a second pixel electrode, and a third pixel electrode formed on the substrate; a first bank layer and a second bank layer formed on the substrate; and a first organic light emitting layer, a second organic light emitting layer, and a third organic light emitting layer formed on the first pixel electrode, the second pixel electrode, and the third pixel electrode, respectively. The first organic light emitting layer overlaps the second organic light emitting layer on the first bank layer.
