1. An organic light emitting diode display device, comprising:
- a substrate;
a passivation layer on the substrate and including a trench and a recessed portion;
a first electrode on the passivation layer such that the passivation layer is between the substrate and the first electrode;
a pixel defining layer on the passivation layer, the pixel defining layer defining an opening which exposes at least a part of the first electrode;
an organic light emitting layer on the first electrode; and
a second electrode on the light emitting layer,wherein the recessed portion is in an area bounded by edges of the opening and is spaced apart from the edges of the opening, andwherein the trench is spaced apart from the first electrode, the pixel defining layer being disposed above the trench.

Abstract
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.
