Liquid crystal display device

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;
• a thin film transistor formed in said pixel regions, and driven by a scanning signal from a scanning signal line for supplying video signal from one of the video signal lines to a pixel electrode;
• a display area containing a plurality of said pixel regions;
• a first protection element line formed at a peripheral portion of said display area, and being connected to odd-numbered one of said video signal lines by first high-resistance elements;
• a second protection element line formed at a peripheral portion of said display area, and being connected to even-numbered ones of said video signal lines by second high-resistance elements;
• and
• a common line electrically connected to said first and second protection element lines by third high-resistance elements.
