Abstract: A liquid crystal display device includes a gate electrode; a gate insulating layer on the gate electrode; an active layer on the gate insulating layer corresponding to the gate electrode; source and drain electrodes on the active layer; a first passivation layer on the source and drain electrodes; a common electrode on the first passivation layer; a second passivation layer on the common electrode, covering the common electrode, and having a separate region from the first passivation layer at a thickness of the common electrode; a pixel electrode on the second passivation layer and connected to the drain electrode through a drain contact hole; and a common line at a same layer as the pixel electrode and connected to the common electrode.
