  • Patent number: 9207509
    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.
