ABSTRACT:
Each cell of a liquid crystal display comprises a pixel electrode, a primary field effect transistor for transferring electrical signals from one scan line and one data line to the pixel for conversion to an optical signal and at least one auxiliary field effect transistor for transferring signals from a scan line adjacent to the one scan line and from the one data line to the pixel when the primary field effect transistor is defective. The auxiliary FET gate electrode is electrically isolated from the adjacent scan line when the primary FET is not defective and may be connected to the adjacent scan line by activating a laser-fusible link if the primary FET is defective. Redundant scan line crossovers and redundant data line crossover are provided, with each redundant crossover having an open circuit that may be closed by a laser-fusible link to create a shunt around a selected scan and data line crossover location, if the scan line and data line are shorted together at that crossover location.
