Abstract:
A method for manufacturing a liquid crystal display panel includes coating a resin film on one of a pair of substrates facing each other and patterning the resin film to form pillar spacers. The surface of the substrate where the pillar spacers have been formed is optically cleaned, and alignment film is formed on the optically cleaned substrate. In the optical cleaning process, a light source having an emission peak in a wavelength range of 180 nm or less, or 260 nm or more, and not having an emission peak in a wavelength range from 180 nm to 260 nm is used.
