Liquid crystal display and method of manufacturing the same
First Claim
1. 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 placed at an end portion of the gate bus line, with a first conductive material on a substrate;
sequentially depositing a first insulating material, an intrinsic semiconductor material, a doped semiconductor material and a second conductive material on the gate bus line, the gate electrode and the gate pad;
patterning the second conductive material 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;
forming a semiconductor layer, a gate insulating layer, and a gate pad protecting layer covering a first portion of the gate pad, by simultaneously patterning the intrinsic semiconductor material and the first insulating material, the gate pad protecting layer including a portion of the first insulating material and the semiconductor material; and
forming a passivation layer 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.

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.
