ABSTRACT:
An active matrix-type liquid crystal display is described having, for each pixel, a first electrode for of a storage capacitor that is connected to a scanning signal line. The liquid crystal display can be repaired for disconnections and short inferiorities occurring in a crossing portion of scanning signal line. A redundancy correcting line connects the capacitor electrodes of adjacent pixels. Also described is a double scanning signal line. The embodiments using the redundant connecting line and double scanning signal line are both repairable using laser if imperfections exist. Thus, while maintaining high aperture and contrast ratios, the disconnections and shorts in the crossing portion of wirings can be minimized.
