Abstract
An array substrate of a liquid crystal display and a fabricating method thereof. In the array substrate, a gate wire and a common wire are provided on the substrate. A gate electrode is protruded from the gate wire. A gate insulating film is formed in such a manner to cover the gate wire and the gate electrode. A source electrode is provided on a semiconductor layer and a gate insulating film and is connected to a data wire. A drain electrode is provided on the semiconductor layer and the gate insulating film and is opposed to the source electrode. A protective layer covers the gate and data wires and the source and drain electrodes, and has a contact hole for exposing the drain electrode. A pixel electrode is connected, via the contact hole, to the drain electrode. Herein, the drain electrode is extended within a pixel to overlap with the common wire having the gate insulating film therebetween.
