Abstract
An LCD device and a method for manufacturing the same is disclosed in which the manufacturing process is simplified by etching an overcoat layer and a lower insulating layer at the same time. Disclosed is a method for manufacturing the LCD device that includes forming a thin film transistor (TFT) on an active region of a substrate, forming a gate pad region and data pad region, and forming a passivation layer on the entire surface of the substrate. The manufacturing method further includes forming an overcoat layer and selectively etching the overcoat layer. Contact holes for the pixel electrode, the gate pad, and the data pad are formed by selectively etching the overcoat layer, the passivation layer, and the gate insulating layer though one process.
