Patent ID: 7129999

Claim:
A liquid crystal display device comprising: a first substrate; a second substrate; a liquid crystal layer interposed between said first substrate and said second substrate; a plurality of video signal lines and scanning signal lines formed on said first substrate, and delimiting pixel regions; plural video signal line driving circuits electrically connected with said video signal lines; a thin film transistor formed above each of said pixel regions, and driven by a scanning signal from scanning signal line for supplying a video signal from one of the video signal lines to a pixel electrode; a display area containing a plurality of said pixel regions; a protection element line formed above a peripheral portion of said display area, and being connected to at least one of said video signal lines by at least one protection element; a plurality of counter signal lines formed above said display area and connected to a storage capacitor; at least one common line formed above a peripheral portion of said display area and electrically connected with at least one of said counter signal lines; a first circuit board electrically connected with a plurality of said plural video signal line driving circuits for supplying a video signal to a left side of said display area; and a second circuit board electrically connected with another plurality of said plural video signal line driving circuits for supplying a video signal to a right side of said display area; wherein said at least one common line is electrically connected with said protection element line by at least one high-resistance element.
