Patent

CA 2040306

The disclosure deals with color filters used in liquid crystal devices and, more particularly, with the repair of defects. When a given defect is one color, the defective portion is filled with a negative type photosensitive resin of the same color as the defective pixels. When a defect extends over pixels of various different colors, the defective area is filled with a negative type photosensitive resin of gray. Repair is readily effected since self-alignment can be achieved using the filter as a photomask.
