ABSTRACT:
An active matrix type liquid crystal display panel comprises a first substrate, a second substrate, and a liquid crystal layer sandwiched by these two substrates. A plurality of gate signal lines and a plurality of source signal lines are provided on the dielectric first substrate in such a manner to intersect with each other, and thin film transistors for driving pixels are provided to the intersections of these lines individually. A short-circuit remaining line is made on the first substrate at its end portion at a predetermined distance from the end portion of each line while being electrically connected to a common electrode formed on the second substrate. This arrangement makes it possible to prevent static-induced damages to the liquid crystal display panel not only before, but also after cutting the connection between the gate and source signal lines and the short-circuit wiring provided to short-circuit these signal lines.
