Abstract:
1. A liquid crystal display device, comprising: first and second substrates facing and spaced apart from each other; a gate line, a data line, and a common line on an inner surface of the first substrate, the gate line crossing the data line to define a pixel region, the common line parallel to the gate line; a thin film transistor connected to the gate line and the data line; a passivation layer on the gate line, the data line, the common line, and the thin film transistor, the passivation layer including a common contact hole exposing the common line and a drain contact hole exposing a drain electrode of the thin film transistor; a plurality of insulating patterns on the passivation layer; a plurality of pixel electrodes and a plurality of common electrodes on the plurality of insulating patterns, the plurality of pixel electrodes alternating with the plurality of common electrodes, the adjacent pixel and common electrodes generating a horizontal electric field according to a driving voltage, the plurality of common electrodes being connected to the common line through the common contact hole, the plurality of pixel electrodes being connected to the drain electrode of the thin film transistor through the drain contact hole, the plurality of pixel electrodes and the plurality of common electrodes being formed on the passivation layer and on the plurality of insulating patterns; and a liquid crystal layer between the first and second substrates, the liquid crystal layer including blue phase liquid crystal molecules, wherein the blue phase liquid crystal molecules are stabilized by a polymer, wherein the polymer is combined with the blue phase liquid crystal molecules having no directional property rather than the blue phase liquid crystal molecules having a directional property, wherein the polymer comprises an acrylic co-polymer comprising a co-polymer of a carboxylic monomer and a monomer co-polymerizable with the carboxylic monomer, and wherein each of the plurality of insulating patterns has a thickness corresponding to a cell gap between the first and second substrates so that the plurality of insulating patterns can maintain the cell gap.
