An organic light emitting diode display device includes a passivation layer, a first electrode, a pixel defining layer, an organic emitting layer, and a second electrode. The passivation layer includes a trench and a recessed portion. The first electrode is on the passivation layer. The pixel defining layer is on the passivation layer and defines an opening which exposes at least a part of the first electrode. The organic light emitting layer is on the first electrode. The second electrode is on the light emitting layer. The recessed portion overlaps the opening and is spaced apart from an edge of the opening. The trench is spaced apart from the first electrode.
