Abstract

A method of a color filter substrate for a semitransmissive type liquid crystal display device, including: forming a photosensitive coloring composition layer containing a photo-polymerizable monomer, a resinous binder, a polymerization initiator, a coloring agent and a solvent on a surface of a transparent substrate, the surface being partitioned into a large number of pixel regions; exposing the photosensitive coloring composition layer to light; and developing the photosensitive coloring composition layer to form a transmissive portion and a reflective portion, the transmissive portion being assigned to colorize a transmitted light from a light source arranged on a rear surface side of a liquid crystal display device, the reflective portion being assigned to colorize a reflected light to be derived from reflection of an external light entering from the observer's side and having a through-hole with a diameter of 10 μm or less.
