Patent ID: 6839114

Claim:
An in-plane switching liquid crystal display device, comprising: first and second substrates; a gate line and a data line defining a pixel region on the first substrate; a common line parallel to and spaced apart from the gate tine in a middle section of the pixel region; a thin film transistor adjacent to a crossing portion of the gate and data lines, the thin film transistor having gate, source, and drain electrodes; a first insulating layer on the gate line and common line; a transparent common electrode on the first substrate and having a plurality of extended portions perpendicular to the common line; a plurality of transparent pixel electrodes on the first substrate and having a plurality of extended portions perpendicular to the common line; extended portions extending from the common line between a boundary of the pixel region and an outermost extended portion of the common electrode, wherein the extended portions extending from the common line are on a layer different from the common electrode; a first storage electrode on the first insulating layer over the common line; a second storage electrode on the first insulating layer over the gate line, wherein the first and second storage electrodes are connected to the drain electrode by extended lines on a layer different than the pixel electrodes; and a liquid crystal layer between the first and second substrates, wherein the plurality of extended portions of the pixel electrodes have an alternating pattern with the plurality of extended portions of the common electrode.
