Claim:
1. A manufacturing method of a display device, comprising: forming a gate member and a common electrode line on a substrate; forming a gate insulating layer on the gate member and the common electrode line; forming a semiconductor member and a data member on the gate insulating layer; forming a first passivation layer on the semiconductor member and the data member; forming a plurality of color filters on the first passivation layer; forming a conductor layer and a second passivation layer on the plurality of color filters; forming a first contact hole through which a common electrode is exposed, wherein the common electrode includes the conductor layer and the common electrode line, and forming a second contact hole through which a drain electrode is exposed, wherein the first and second contact holes are formed by etching the second passivation layer, the conductor layer, the first passivation layer, and the gate insulating layer in a single step using a photolithography process; and forming a pixel electrode connected to the drain electrode through the first contact hole, and forming a connecting member connected to the common electrode line and the common electrode through the second contact hole, wherein the pixel electrode and the connecting member are formed substantially simultaneously.
