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: Disclosed are a liquid crystal display device and a method for fabricating the same. The liquid crystal display device includes first and second substrates joined to and facing each other, a TFT formed in each pixel of an active area on the first substrate, a first discharge line formed in a non-active area on the first substrate, a protective layer formed over the entire surface of the first substrate, including the TFT and the first discharge line, a second discharge line surrounding an outer region of the first discharge line in the non-active area on the first substrate, a plurality of contact holes passing through the protective layer to expose a portion of the first discharge line, a connection pattern branching from the second discharge line, and covering the respective contact holes, and an electrostatic discharge layer formed on the outside surface of the second substrate.
