Abstract: An organic light emitting diode display device includes a substrate, a first oxide transistor, a second oxide transistor, and a sub-pixel structure. The substrate has a display region including a plurality of sub-pixel regions and a peripheral region located in a side of the display region. The first oxide transistor is disposed in the peripheral region on the substrate, and includes a first oxide semiconductor pattern that includes tin (Sn). The second oxide transistor is disposed in the sub-pixel regions each on the substrate, and includes a second oxide semiconductor pattern. The sub-pixel structure is disposed on the second oxide transistor.
