Abstract: A liquid crystal display device includes a light shield layer formed on the display electrode (3) at the edge of each display aperture as a thin layer (5) at the upstream edge of the aperture in the rubbing direction of the device, and a thick layer (4) formed on the thin layer at a spacing (L) from the boundary of the display aperture. This leaves a thin light shield over the part of the display cell having reverse tilted liquid crystal molecules, thereby enhancing the quality of the display.

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.
