Abstract:
1. A thin film transistor array substrate comprising: a substrate; a gate line intersecting a data line to define a pixel region on the substrate; a switching element disposed at an intersection of the gate line and the data line; a plurality of second pixel electrodes and a plurality of first common electrodes alternately arranged in the pixel region; a second common electrode disposed on an organic insulation film, wherein the second common electrode is overlapped with the data line, wherein the data line is interposed between a gate insulation film and a protective film; a first storage electrode on the substrate; a second storage electrode overlapping the first storage electrode; and a first pixel electrode connected to the second storage electrode through a contact hole, wherein the organic insulation film is formed on the switching element, the second storage electrode, the data line, a gate pad, and a data pad, and wherein the second common electrode covers the data line, the protective film, the organic insulation film, and the gate insulation film disposed under the data line, and has inclined surfaces connected to the surface of the substrate, and wherein a thickness of the organic insulation film formed over the switching element, the second storage electrode, the gate pad, and the data pad is smaller than that of the organic insulation film formed over the data line.
