Patent ID: 7112512

Claim:
A method of manufacturing a liquid crystal display, comprising the steps of: forming a first conductive layer on a substrate; patterning the first conductive layer to form a gate line with a gate line, a gate electrode and a gate pad; forming a gate insulating layer, a semiconductor layer, a doped semiconductor layer and a second conductive layer on the gate line; forming a photoresist pattern with various thicknesses on the second conductive layer, wherein said photoresist pattern is a layer unexposed in a certain thickness over said gate pad and said gate electrode; providing stepwise etching on said second conductive layer, said doped semiconductor layer, and a portion of said semiconductor layer so as to form a data line with source electrode and a drain electrode; forming an organic protection layer, patterning said organic protection layer to form a plurality of through holes; and forming a third conductive layer in said through holes electrically connected to said second conductive layer.
