A thin film transistor liquid crystal display compensates for differences in optical brightness of pixels associated with normal data lines and repaired data lines. The display includes signal delay elements formed in the signal receiving portions of the data lines so as to provide a built-in signal delay to match the signal delays created in the display arising when data lines are repaired. Auxiliary signal lines are formed in parallel with, but initially insulated from the signal delay elements. When a data line is repaired, the auxiliary data line is shorted across the terminals of the signal delay element so as to remove that source of delay from the repaired data line signal path. Preferably, the signal delay through the repaired data line without a signal delay element in its path will be about the same as a normal data line with a signal delay element.
