Abstract: A touch-panel liquid-crystal display device in one embodiment includes a metal line formed on a thin-film transistor array substrate, a gap column spacer and a push column spacer on a portion of a color filter array substrate that corresponds to an intersection of gate and data lines of the thin-film transistor array substrate, and a liquid-crystal layer between the thin-film transistor array substrate and the color filter array substrate. The gap column spacer and the push column spacer have the same height and the gap column spacer is located on the metal line, which facilitates an exposure process, minimizes generation of foreign substances when printing an alignment layer, and enables adjustment of the optimum amount of liquid crystals when liquid-crystal dotting is performed. The push column spacer is located on the metal line when the device can be pushed or bent by external force, and thus increases panel rigidity.

Abstract: The present invention relates to a rubbing machine with realigning functions for use in an LCD manufacturing process and also to a rubbing method which is conducted using the same. The rubbing machine is used to determine the direction of alignment by rubbing an alignment film coated on a substrate disposed on a stage. In this rubbing machine, an realigning section for realigning a rubbing cloth is disposed on the portion of a rubbing roll in such a manner that the realigning section be in contact with the rubbing cloth.

Abstract: Disclosed is a conductive polarizer for a liquid crystal display device. The conductive polarizer comprises: an adhesive layer composed of acrylic materials and conductive materials, the adhesive layer being formed on a substrate; a lower supporting layer formed on the adhesive layer; a polarizer element formed on the lower supporting layer; and an upper supporting layer formed on the polarizer element. Therefore, the occurrence of inferior products, resulting from static electricity arising during attachment of the polarizer can be largely reduced. Furthermore, because the number of ionizers included with the attachment device for the polarizer can be decreased and substituted with other devices, a conductive polarizer of a liquid crystal display device can be produced at low cost.
