Abstract
A method of manufacturing a liquid crystal display device includes the steps of forming a transparent electrode on a surface of a substrate, patterning the transparent electrode, coating a photosensitive layer of resin on the patterned transparent electrode, radiating ultraviolet radiation on a region of the photosensitive layer which will serve as a spacer to provide a gap between the substrate and a companion substrate to be combined therewith, radiating weak ultraviolet radiation on the photosensitive layer from the reverse side of the substrate, and developing the photosensitive layer to form the spacer and an alignment film simultaneously.
