Patent ID: RE39211

Claim:
A method for manufacturing a liquid crystal display, comprising the steps of: forming a gate electrode and a gate pad by depositing a first metal film and a second metal film over a substrate in a TFT area and a gate-pad connecting area, respectively, by a first photolithography process; forming an insulating film over the gate electrode and the gate pad; forming a semiconductor film pattern over the insulating film in the TFT area by a second photolithography process; forming a source electrode/drain electrode and pad electrode in the TFT portion and pad portion, respectively, using a third photolithography process, the source electrode/drain electrode and pad electrode all being comprised of a third metal film; forming a passivation film pattern by a fourth photolithography process, the passivation film exposing a portion of the drain electrode, a portion of the gate pad, and a portion of the pad electrode; exposing the first metal film by etching a portion of the second metal film that comprises the gate pad using the passivation film pattern as a mask; and forming a pixel electrode connected to the drain electrode of the TFT area by a fifth photolithography process, the pixel electrode acting to connect the gate pad of the gate-pad connecting area to the pad electrode of the pad area.
