Abstract

A display device includes: a substrate; a thin-film transistor disposed on the substrate and including a semiconductor layer; an interlayer insulating layer disposed on the thin-film transistor; a data conductive layer disposed on the interlayer insulating layer and including an auxiliary electrode and a transistor electrode connected to the semiconductor layer of the thin-film transistor, a via layer disposed on the data conductive layer; a pixel electrode layer disposed on the via layer and including: a pixel electrode and a dummy pixel electrode separated from the pixel electrode; an intermediate layer disposed on the pixel electrode layer; and a common electrode disposed on the intermediate layer. The auxiliary electrode includes a main conductive layer and an upper sub-conductive layer. Side surfaces of the main conductive layer of the auxiliary electrode are disposed inner than side surfaces of the upper sub-conductive layer of the auxiliary electrode.
