Patent ID: 8642233

Claim:
A method of manufacturing a color filter substrate for a semitransmissive type liquid crystal display device, comprising: forming a photosensitive coloring composition layer containing a photo-polymerizable monomer, a resinous binder, an oxime ester-based polymerization initiator, a coloring agent and a solvent on a surface of a transparent substrate, said 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, said 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, said 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, wherein the photosensitive coloring composition contains a polymerization inhibitor represented by the following chemical formula (1) and an organic pigment, and has an exposure sensitivity property in which contrast γ (=tan θ) is confined to 1.33 or more and a residual rate of a film of the photosensitive coloring composition after development is 0% at an exposure dose of not more than 23% of the minimum exposure dose that makes the residual rate of the film not lower than 85%, when a rising angle of an exposure sensitivity curve is defined as 0 in the exposure sensitivity curve to be derived by plotting exposure sensitivity in coordinates with an abscissa thereof representing common logarithm of the exposure dose and with an ordinate thereof representing the residual rate of the film after development where R 1 is hydroxyl group or alkoxy group, and R 2 is C n H 2n+1 (n=0-4).
