Abstract (en)

[origin: DE19756082A1] A process for repairing the row and column lines of an active matrix liquid crystal display allows line interruptions to be repaired already during manufacture of the display. Insulating layers between the row and column lines are etched only after their structuring, also exposing contact holes through which an electrical connection between the interrupted line and a repair line can be established by means of a conductive layer for the picture point electrodes.
