Abstract:
1. An array substrate for a fringe field switching mode liquid crystal display device, comprising: a gate line on a substrate; a gate electrode connected to the gate line; a gate insulating layer on the gate line and the gate electrode; a semiconductor layer on the gate insulating layer and corresponding to the gate electrode; source and drain electrodes on the semiconductor layer and spaced apart from each other, the source electrode having first and second sub-source layers, the drain electrode having first and second sub-drain layers, wherein one side portion of the first sub-source layer has an identical end line with one side portion of the semiconductor layer, and one side portion of the first sub-drain layer has an identical end line with the other side portion of the semiconductor layer, and wherein the second sub-source layer covers an upper surface and a side surface of the first sub-source layer, and the second sub-drain layer covers an upper surface and a side surface of the first sub-drain layer; a data line having a double-layered structure and crossing the gate line to define a pixel region; a pixel electrode in the pixel region and extending from the second sub-drain layer; a passivation layer on the pixel electrode; and a common electrode on the passivation layer and having at least one opening corresponding to the pixel electrode.
