Patent ID: 7349036

Claim:
A liquid crystal display device, comprising: a first substrate and a second substrate; a liquid crystal layer between the first substrate and the second substrate; a pixel electrode over the first substrate and a common electrode over the second substrate, the pixel electrode and the common electrode facing each other to apply an electric field to the liquid crystal layer; a plurality of lower electrodes extending along a first direction on the first substrate, the lower electrodes include first and second opposing edge regions and a central region; an insulating layer on the lower electrodes; and a plurality of upper electrodes on the insulating layer to overlap with the lower electrodes to form a first overlapping area at the first and second edge regions in each facing lower electrode and the upper electrode, wherein perimeters of the upper electrodes protrude from the first and second edge regions, a second overlapping area at the central region of the lower electrodes, and a plurality of opening regions exposing the insulation layer over the central region on the lower electrodes, wherein the area of the opening regions are the same as each other over the whole lower electrodes.
