The present invention relates to a liquid crystal display, wherein arrangement of liquid crystal molecules thereof is controlled by using a monomer that is polymerized by ultraviolet rays to provide a pre-tilt. To prevent damage to organic material layers when irradiating ultraviolet rays to the monomer, a blocking film made of an ultraviolet absorbing agent is formed on or over at least one such layer.
