Abstract
In an active matrix liquid crystal display device an internal short circuiting bus is formed across source and gate buses outside of a display region where thin film transistors and pixel electrodes are respectively arranged in a matrix form and inside of arrays of source and gate bus terminals. At intersections of the internal short circuiting bus with the source bus and the gate bus coupling elements of a high resistance material are provided for connecting the internal short circuiting bus to the source bus and the gate bus, respectively.
