Abstract:
1. An IPS-LCD device, comprising: first and second substrates opposing each other; a gate line on the first substrate; a data line perpendicular to the gate line; a thin film transistor at a crossing portion between the gate and data lines; a common line parallel to the gate line; a plurality of common electrodes electrically connected to the common line, wherein the common electrodes are spaced apart from each other and covered by a gate-insulating layer; a plurality of pixel electrodes alternately arranged with the plurality of common electrodes, wherein each pixel electrode is spaced apart from an adjacent common electrode and covered by a passivation layer; a plurality of dielectric protrusions between the first and second substrates, wherein the dielectric protrusions are chevron-shaped dielectric protrusions that cross the plurality of common and pixel electrodes; and a liquid crystal layer between the first and second substrates, wherein the liquid crystal layer and the dielectric protrusion have different dielectric constants.
