In an active matrix liquid crystal display device in which a counter electrode is formed, at least one scan-side dummy line is formed on the one substrate on both sides of the scan line group and parallel to the scan line. , at least one line parallel to the data lines and located on each side of the data line group.
one data-side dummy line is provided, the scanning-side dummy line and the data-side dummy line are short-connected to each other at their ends, and both ends of the scanning line are extended to the outside of the data-side dummy line. An active matrix liquid crystal display device characterized in that the data line has both ends extending outside the scanning side dummy line.
