Abstract:
1. An array substrate of a liquid crystal display, comprising: a first part of a gate line formed of a first oxidized metal layer on a substrate; a first part of a gate electrode on the substrate, and a first storage electrode extending from the first part of the gate line; a second part of the gate line and a second part of the gate electrode formed on the first part of the gate line and the first part of the gate electrode, respectively, and formed of a first metal layer; a gate insulating film entirely formed on the gate line, the gate electrode and the first storage electrode; a semiconductor layer formed on the gate insulating film to partially overlap with the gate electrode and the gate line; a first part of a data line formed on the semiconductor layer and formed of a second oxidized metal layer; a first part of a source electrode formed at one end of the semiconductor layer and extending from the data line; a first part of a drain electrode formed at another end of the semiconductor layer and separated from the source electrode; a second storage electrode overlapping the first storage electrode with the gate insulating film therebetween; a second part of the data line, a second part of the source electrode, and a second part of the drain electrode formed of a second metal layer, and formed to overlap with the first part of the data line, the first part of the source electrode and the first part of the drain electrode, respectively; an organic insulating film covering the data line, the source electrode, the drain electrode and the second storage electrode; and a pixel electrode in contact with the second part of the drain electrode and the second storage electrode respectively through a first contact hole and a second contact hole formed in the organic insulating film.
