Organic light emitting display device and method of manufacturing the same

An organic light emitting display (OLED) device, comprising:

• a substrate;
• a first pixel electrode, a second pixel electrode, and a third pixel electrode each overlapping the substrate;
• a pixel defining layer comprising a first opening, a second opening, and a third opening respectively partially exposing the first pixel electrode, the second pixel electrode, and the third pixel electrode, wherein the pixel defining layer further comprises a first uneven surface, a first flat face, a second uneven surface, and a second flat face, wherein the first uneven surface is positioned in an opposite side to the first flat face in a first direction and is positioned between the first opening and the second opening, wherein the first flat face is positioned between the first pixel electrode and the second pixel electrode and is positioned between the first uneven surface and the substrate, wherein the second uneven surface is positioned in an opposite side to the second flat face in the first direction and is positioned between the first opening and the third opening, and wherein the second flat face is positioned between the first pixel electrode and the third pixel electrode and is positioned between the second uneven surface and the substrate;
• a first emission layer, a second emission layer, and a third emission layer respectively corresponding to the first opening, the second opening, and the third opening;
• a common electrode overlapping each of the first emission layer, the second emission layer, and the third emission layer;
• and
• a spacer disposed between the pixel defining layer and the common electrode and positioned between the second opening and the third opening.
