Abstract: A color liquid crystal display having chromatic pixels and achromatic pixels, comprises: color filters (12, 14, 16) formed at locations corresponding to said chromatic pixels (13, 15, 17) and having a light transmitting area for predetermined wavelength; and translucent filters (18) formed at locations corresponding to said achromatic pixels (19) and near an outer periphery of locations corresponding to said chromatic pixels so as to be overlapped with said color filters.

Abstract: 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.
