Abstract
An organic light emitting diode display device includes a substrate including a pixel portion and a peripheral portion, a semiconductor layer including a pixel switching semiconductor layer and a driving semiconductor layer formed on the pixel portion, and a peripheral switching semiconductor layer formed on the peripheral portion. A first gate insulating layer is formed on the semiconductor layer. A peripheral switching gate electrode is formed on the first gate insulating layer of the peripheral portion, and a pixel switching gate electrode and a driving gate electrode are formed on the first gate insulating layer of the pixel portion. A length of a peripheral switching low concentration doping region formed in the peripheral switching semiconductor layer may be larger than a length of a pixel switching low concentration doping region and a driving low concentration doping region formed in the pixel switching semiconductor layer and the driving semiconductor layer, respectively.
