Abstract
An OLED display device is provided. The OLED display device includes a substrate segmented into a plurality 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, 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.
