Abstract:
1. A liquid crystal display device, comprising: a gate line formed on a first substrate; first and second adjacent data lines crossing the gate line to form adjacent pixel regions in an extended direction of the gate line; a pixel electrode line in parallel with the first data line in each of the pixel regions; a plurality of pixel electrodes formed to be protruded in the extended direction of the gate line from the pixel electrode line; a common line disposed in parallel with the first and second adjacent data lines, preventing cutting off a data signal; a plurality of common electrodes alternately formed in parallel with the plurality of pixel electrodes and generating an in-plane electric field therebetween, the common electrodes being connected to the common line; an auxiliary common electrode portion formed at both end portions of the common electrode to be protruded along an extended direction of the common line at a region where one of the common electrodes and the common line are connected, the auxiliary common electrode portion being formed at a lower portion of a region where the pixel electrode and the pixel electrode line are connected at an acute angle; and an alignment film having a rubbing direction perpendicular to the first data line, wherein the adjacent pixel regions are driven by a horizontal two-dot inversion system.
