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.
