Abstract: An organic light emitting diode display device includes a substrate, a buffer layer, a first circuit structure, a sub-pixel structure, and a first signal wire. The substrate includes a display region including a plurality of sub-pixel regions and a peripheral region surrounding the display region. The buffer layer is disposed in the display region and peripheral region on the substrate. The first circuit structure is disposed in the peripheral region on the buffer layer. The sub-pixel structure is disposed in each of the sub-pixel regions on the first circuit structure. The first signal wire is disposed in the peripheral region between the substrate and the buffer layer, and overlaps the first circuit structure when viewed from a plan view in a thickness direction of the substrate.
