Patent ID: 7180563

Claim:
An array substrate for an in-plane switching mode liquid crystal display device, comprising: a substrate; a gate line on the substrate; a common line on the substrate, the common line being parallel to and spaced apart from the gate line; a common electrode on the substrate, the common electrode including: a plurality of first vertical portions perpendicularly extended from the common line; and a first horizontal portion combining the plurality of first vertical portions; a gate insulating layer on the gate line, the common line and the common electrode; a data line on the gate insulating layer, wherein two of the plurality of first vertical portions of the common electrode adjacent the data line overlap the data line; a thin film transistor connected to the gate line and the data line, the thin film transistor including an active layer, source and drain electrodes; a pixel electrode directly on the gate insulating layer, the pixel electrode including: an extended portion extended from the drain electrode; a plurality of second vertical portions perpendicularly extended from the extended portion; and a second horizontal portion combining the plurality of second vertical portions and overlapping the common line and an adjacent gate line, wherein there is a non-overlapping space between the first vertical portions of the common electrode adjacent the data line and the second vertical portions of the pixel electrode adjacent the first vertical portions adjacent the data line; and a single passivation layer covering only the thin film transistor, wherein the extended portion, the plurality of second vertical portions and the second horizontal portion of the pixel electrode are exposed.
