The invention provides an organic light emitting diode display device and a method of fabricating the same. The OLED display device comprises a first oxide semiconductor layer comprises a first area, a second area, a third area and a fourth area; a first insulation layer located on the first oxide semiconductor layer; a first grid electrode that is located on the first insulation layer and completely coincides with the first area; a first storage electrode that extends from the first grid electrode and coincides with the second area; a second insulation layer covering the first grid electrode and the first storage electrode and exposing the third area and the fourth area; a first source electrode and a drain electrode which are located on the second insulation layer and are in contact with the third area and the fourth area; a light emitting diode connected to the first drain electrode. Part of the second area at the edge of the first storage electrode beyond the center of the first storage electrode is conductive, so that a second storage electrode is formed. The first storage electrode, the second storage electrode and the first insulation layer form a first storage capacitor.
