Abstract
An organic light emitting diode display device includes a substrate; a thin film transistor on the substrate; a first electrode on the thin film transistor and connected to a drain electrode of the thin film transistor; 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 to the first electrode and an auxiliary contact hole corresponding to the auxiliary electrode; a light emitting layer on the first electrode in the transmissive hole; a residual layer on the auxiliary electrode in the auxiliary contact hole, wherein a thickness of a central portion of the residual layer is smaller than a thickness of an edge portion of the residual layer; and a second electrode on the light emitting layer and the residual layer.
