Abstract:
1. An organic light emitting diode (OLED) display device, comprising: a substrate segmented into a plurality of sub-pixel regions; a thin film transistor formed in each of the sub-pixel regions; an insulating layer and a planarization layer formed on the thin film transistor; a semitransparent reflective layer selectively formed in each sub-pixel region on the planarization layer, and comprising a transparent layer and a semitransparent metal layer; a protective layer formed on the semitransparent reflective layer; an anode electrode formed in a region corresponding to the semitransparent reflective layer on the protective layer, and connected to the thin film transistor; an organic light emitting layer connected to the anode electrode, and emitting light; and a cathode electrode formed on the organic light emitting layer, wherein the semitransparent reflective layer is formed to be interposed between the planarization layer and the organic light emitting layer.
