Abstract: An organic light emitting diode display device, and method of fabricating an organic light emitting diode display device are discussed. The organic light emitting diode display device according to one embodiment includes a first electrode on a thin film transistor and connected to a drain electrode; an auxiliary electrode on a same layer as the first electrode; a bank layer covering edges of the first electrode and edges of the auxiliary electrode and having a transmissive hole corresponding and an auxiliary contact hole; a light emitting layer on the first electrode in the transmissive hole; a residual layer on the auxiliary electrode in the auxiliary contact hole. A central portion of the residual layer has a larger thickness than an edge portion of the residual layer. The organic light emitting diode display device further includes a second electrode on the light emitting layer and the residual layer.
