Abstract:
1. A method of fabricating an array substrate for a liquid crystal display device, comprising: preparing a substrate having a display area and a driving circuit area; forming a first semiconductor layer in the display area of the substrate; forming a first gate insulating layer on the first semiconductor layer; forming a first gate electrode on the first gate insulating layer, the first gate electrode being wider than the first gate insulating layer; doping the first semiconductor layer with one of a high concentration impurities of a negative type (n forming a first interlayer insulating layer over the substrate including the first gate electrode, wherein the first interlayer insulating layer, the first gate electrode, the first gate insulating layer, and the first active region define a first cavity, wherein the first cavity is not filled with the interlayer insulating layer.
