A array substrate and method for manufacturing thereof and liquid panel having the same

The array substrate and a method of manufacturing the same, and a liquid crystal panel having him to remove the bad pixel is disclosed. The array substrate comprises an insulating layer and a pixel electrode layer having a switching element, and a contact hole. The switching device has a gate connected with the gate wiring is formed on a substrate electrode, forming a channel layer on the gate electrode and the expanded semiconductor layer in a first direction and a source electrode connected to the source wiring and the insulating layer is a part of the drain electrode and It has a contact hole formed to expose the substrate. The pixel electrode is connected to the drain electrode through the contact hole. The contact hole can be prevented by having the first of the drain electrode 2 exposed portion to expose the exposed portion, and all or a portion of the exposed drain electrode and the substrate adjacent to the pattern defect for exposing a portion of the drain electrode. Contact hole structure, the semiconductor layer, the drain electrode, U-shaped
