Abstract:
A method of manufacturing a liquid crystal display comprising the steps of:forming a gate bus line, a gate electrode extending from the gate bus line, and a gate pad at an end portion of the gate bus line, with a first conductive material on a substrate; forming a gate insulating layer, a semiconductor layer, a doped semiconductor layer, and a gate protecting layer covering a first portion of the gate pad, by sequentially depositing and patterning a first insulating material, an intrinsic semiconductor material, and a doped semiconductor material on the gate bus line, the gate electrode, and the gate pad; forming a source electrode, a drain electrode, a source bus line, and a source pad with a second conductive material over the substrate including the doped semiconductor layer; and forming a passivation layer by depositing a second insulating material over the substrate including the source bus line, the source electrode, the drain electrode, and the source pad, and patterning the passivation layer to expose a second portion of the gate pad and the gate pad protecting layer.
