Abstract
A liquid crystal display includes a gate bus line, a gate electrode extending from the gate bus line, and a gate pad placed at an end portion of the gate bus line with a first conductive material formed on a substrate. A first insulating material, an intrinsic semiconductor material, a doped semiconductor material and a second conductive material are sequentially deposited on the gate bus line, the gate electrode, and the gate pad. The second conductive material is patterned to form a source bus line, a source electrode extending from the source bus line, a drain electrode, and a source pad at an end portion of the source bus line. A semiconductor layer, a gate insulating layer, and a gate protecting layer covering a first portion of the gate pad are formed by simultaneously patterning the intrinsic semiconductor material and the first insulating material. A passivation layer is formed by depositing a second insulating material over the substrate, 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.
