Patent ID: 7495733

Claim:
A thin film transistor array substrate, comprising: a gate line; a data line crossing the gate line to define a pixel area; a common line formed in parallel to the data line; a thin film transistor near the crossing of the gate line and the data line; a common electrode connected to the common line and formed in parallel to the gate line at the pixel area; and a pixel electrode connected to the thin film transistor for forming a horizontal electric field with respect to the common electrode, wherein an edge of the pixel electrode overlaps the common line with at least one insulating layer there between, and an edge of the common electrode overlaps the pixel electrode with said at least one insulating layer therebetween, and wherein the pixel electrode includes: a vertical part connected to the thin film transistor in a parallel to the data line and overlapping the edge of the common electrode; and a finger part formed on a plane different from the vertical part in such a manner to be overlapped with the vertical part, thereby making the horizontal electric field with respect to the common electrode.
