An organic light emitting diode display device includes a substrate, a pixel structure, and a wiring pattern. The substrate includes a plurality of pixel regions each having sub-pixel regions and a transparent region. The pixel structure is disposed in the sub-pixel region on the substrate. The wiring pattern is disposed in the transparent region and the sub-pixel region on the substrate, and is electrically connected to the pixel structure. The wiring pattern extends in a first direction that is from the transparent region into the sub-pixel region, and has at least one opening in the transparent region.
