PURPOSE: To provide the liquid crystal display device which decreases the man- hours for production, lowers the disconnection defects generation rate of respective wirings and to lower the resistance of respective wirings relating to the structure of the active matrix type liquid crystal display device constituted by using thin-film transistors (TFTs) switching elements and the process for production of such structure.
CONSTITUTION: Scanning lines for driving TFTs and signal wirings are constituted by simultaneously forming the first signal wirings 17 (b) which are a part of the signal wirings at the time of forming the first scanning wirings 17 (a), further, forming the second scanning wirings 16 (b) which are a part of the scanning wirings at the time of forming the second signal wirings 16 (a) and bringing the respective wirings into electrical contact partially with each other via aperture contact parts 18, 19. As a result, the number of patterning times is decreased and since the respective wirings can be made into redundancy constitution, there are the effect of decreasing man-hours for production, drastically lessening the disconnection defect generation rate of the respective wirings and preventing the delaying of the signals by the lowered resistance of the respective wirings.
