Abstract
An LCD is manufactured to provide a wide viewing angle device and may reduce manufacturing costs according to an embodiment. The LCD includes a substrate, a gate line disposed on the substrate, a gate insulating layer disposed on the gate line, a semiconductor layer disposed on the gate insulating layer, a data line contacting the semiconductor layer, a drain electrode contacting the semiconductor layer and separated from the data line, a pixel electrode contacting the drain electrode, a passivation layer disposed on the pixel electrode, and a common electrode disposed on the passivation layer and including a branch electrode overlapping the pixel electrode. In one embodiment, the pixel electrode contacts an end portion of a thin film transistor. The LCD manufacturing process may be shortened and may save manufacturing costs because the LCD process need not make contact holes to connect the pixel electrode and the TFT.
