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. |

DETAILED DESCRIPTION It is a primary object of the present invention to provide a liquid crystal display to which defects such as wiring fractures of the scanning signal line at the intersection of the scanning signal lines and display signal lines can be corrected.
It is another object of the present invention to provide a liquid crystal display to which defects such as short circuits occurring at the intersection of the scanning signal lines and display signal lines can be corrected.
It is a further object of the present invention to provide a liquid crystal display that improves the aperture ratio.
It is a still further object of the present invention to provide a liquid crystal display that improves the contrast ratio.
It is yet another object of the present invention to provide a method for simply manufacturing the liquid crystal display of the present invention with a minimum number of process steps.
According to the present invention the liquid crystal display contains a plurality of pixel regions bounded by the crossed scanning signal lines and display signal lines.
Each pixel region contains a first electrode, which helps to maintain electric charge within the pixel region, so that the liquid crystal maintains its orientation.
The first electrode is patterned to surround the aperture area containing the liquid crystal material.
In a first embodiment of the invention, each row of adjacent first electrodes are electrically connected together with redundancy connecting conductors.
In a second embodiment, there are two pairs of scanning signal lines associated with each pixel and electrically connected to the first electrode.
In both embodiments, conventional processing techniques without additional process steps are needed.
Furthermore, according to the method of the invention, a laser can be used to correct any short circuits or fractures of the digital signal lines and the scanning signal lines.
Thus, the overall yield can be improved.
