Abstract

See full text

A method for manufacturing a liquid crystal display is provided. The method includes the steps of forming a gate electrode and a gate pad by sequentially depositing a first metal film and a second metal film on a substrate of a TFT area and a pad area, respectively, by a first photolithography process, forming an insulating film on the entire surface of the substrate on which the gate electrode and the gate pad are formed, forming a semiconductor film pattern on the insulating film of the TFT area using a second photolithography process, forming a source electrode and a drain electrode composed of a third metal film in the TFT area using a third photolithography process, forming a protection film pattern which exposes a portion of the drain electrode and a portion of the gate pad on the substrate on which the source electrode and the drain electrode are formed using a fourth photolithography process, and forming a pixel electrode connected to the drain electrode and the gate pad on the substrate on which the protection film pattern is formed using a fifth photolithography process. By using this method it is possible to reduce the number of photolithography steps required for manufacture and to prevent a battery effect and generation of a hillock in the resulting structure.
