Abstract: An organic light emitting diode display device includes a substrate having a plurality of subpixels which each have an emission region and a non-emission region defined along an edge of the emission region. A reflective barrier is disposed to correspond to the non-emission region and includes a reflective side surface. An overcoat layer is disposed on an upper portion of the reflective barrier. A light emitting diode includes a first electrode, an organic light emitting layer, and a second electrode, which are sequentially disposed on the overcoat layer. The reflective side surface of the reflective barrier is inversely tapered such that a width thereof is decreased in a traveling direction of light emitted from the organic light emitting layer.
