DISPLAY DEVICE WITH REDUCED MANUFACTURING COST AND METHOD OF MANUFACTURING THE SAME

摘要

A display device includes a gate line and a data line on a first substrate. A first passivation layer disposed thereon has a first contact hole. A second passivation layer on the first passivation layer has a second contact hole. A common electrode is disposed on the second passivation layer and a residual pattern is disposed on a drain electrode. A third passivation layer, having a third contact hole, is disposed on the common electrode. A pixel electrode, connected to the drain electrode, is disposed on the third passivation layer. A groove is defined between the first and second passivation layers. The common electrode has a open circuit from the residual pattern thereof.

1. A display device comprising:
a first substrate; a gate line and a data line disposed on the first substrate; a first passivation layer disposed on both the gate line and the data line, the first passivation layer having a first contact hole; a second passivation layer disposed on the first passivation layer, the second passivation layer having a second contact hole; a common electrode and a residual pattern of the common electrode, the common electrode being disposed on the second passivation layer and the residual pattern of the common electrode being disposed on a drain electrode; a third passivation layer disposed on the common electrode, the third passivation layer having a third contact hole; and a pixel electrode disposed on the third passivation layer, the pixel electrode being connected to the drain electrode, wherein a groove is defined between the first passivation layer and the second passivation layer, and the common electrode includes an open circuit resulting from the residual pattern of the common electrode.
