Organic light emitting diode display

1. An organic light emitting diode (OLED) display comprising:

a substrate;

a thin film transistor on the substrate;

an organic light emitting diode on the thin film transistor, and including a first electrode connected with the thin film transistor; and

a black organic layer between the thin film transistor and the first electrode, and comprising a black protrusion spaced from the first electrode,

wherein the black protrusion protrudes from a surface of the black organic layer.

2. The OLED display of claim 1 , wherein a top of the black protrusion is farther from the substrate than a top of the first electrode.

3. The OLED display of claim 1 , further comprising a transparent pixel defining layer on the black organic layer, and defining an opening that overlaps at least a part of the first electrode.

4. The OLED display of claim 3 , wherein the transparent pixel defining layer covers the black protrusion.

5. The OLED display of claim 3 , wherein the organic light emitting diode further comprises:

an organic emission layer on the first electrode; and

a second electrode on the organic emission layer, and

wherein the transparent pixel defining layer comprises a side wall that contacts the organic emission layer and defines the opening.

6. The OLED display of claim 5 , wherein the black protrusion is spaced from the organic emission layer.

7. The OLED display of claim 5 , wherein the transparent pixel defining layer is between the black protrusion and the organic emission layer.

8. The OLED display of claim 1 , wherein the black protrusion surrounds the first electrode in a plan view.

9. The OLED display of claim 1 , wherein the black organic layer contacts a bottom side of the first electrode, and

wherein the first electrode contacts the thin film transistor through a hole in the black organic layer.
