A display device includes: a gate electrode, a gate line, and data lines on a substrate, the data lines in a same layer as the gate line; a gate insulating layer on the gate line; a semiconductor member on the gate insulating layer; an etch stopper layer on the semiconductor member and the gate insulating layer; a first passivation layer on the etch stopper layer; a source electrode on the first passivation layer and the etch stopper layer and connected to the data lines; a drain electrode on the etch stopper layer; a common electrode on the first passivation layer and separated from the source electrode and the drain electrode; a second passivation layer on the source electrode, the drain electrode and the common electrode; and a pixel electrode on the second passivation layer and connected to the drain electrode.
