Abstract

A defect correcting method for a liquid crystal panel is disclosed, comprising the step of, when a plurality of pixels are connected, cutting off pixel electrodes of other pixels from a signal supply line in such a way as to drive the other pixels by a TFT of a pixel having a color filter of a highest light transmittance among the plurality of pixels. Another defect correcting method for a liquid crystal panel is disclosed, the liquid crystal panel including a correcting wiring formed beforehand to connect pixels adjacent to each other, comprising the step of: when a defective pixel occurs, electrically connecting a pixel electrode of the defective pixel to that of a pixel adjacent to the defective pixel.
