This invention relates to a method of manufacturing a liquid crystal display panel, wherein a gap between substrates is to be maintained as designed. In a method of manufacturing a liquid crystal display panel, comprising a step of coating a resin film on one of a pair of substrates facing each other and patterning the resin film to form pillar spacers, a step of optically cleaning the surface of the substrate where the pillar spacers have been formed, and a step of forming an alignment film on the optically cleaned substrate, in the optical cleaning, 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.
