Abstract
Pixel areas surrounded by scanning signal lines, video signal lines, and counter signal lines are formed on a liquid-crystal-side surface of a transparent substrate, and include thin-film transistors driven by scanning signals from the scanning signal lines, pixel electrodes to which video signals from the video signal lines are supplied via the thin-film transistors, and counter electrodes spaced apart from the pixel electrodes and connected to the counter signal lines. To prevent leakage current from flowing from the scanning signal lines or the video signal lines to the counter signal lines, a common line is formed around a display area constituted by the pixel areas, the video signal lines and the scanning signal lines are connected to the common line by non-linear elements, and the counter signal lines are connected to the common line by high-resistance elements.
