发明名称 Color filter, method of manufacturing color filter and photosensitive coloring composition
摘要 A color filter comprising a transparent substrate, a light-shielding layer patterned on said transparent substrate, and colored pixels of plural colors patterned on a portion of said substrate where said light-shielding layer is not formed,wherein said colored pixels of at least one color are formed from a photosensitive coloring composition comprising:(A) a pigment;(B) a copolymer of (meth)acrylic acid, as one monomer, and at least one other monomer;(C) a photopolymerizable monomer;(D) a photopolymerizable initiator; and(F) a solvent; andan acid value of a nonvolatile component of said photosensitive coloring composition is 25 through 60 mg KOH/g; and after forming the colored pixels from a photosensitive coloring composition, the light-shielding layer attains reflectance at 380 through 780 nm of 95% or more of reflectance thereof before coating the photosensitive coloring composition; and the transparent portion of the substrate attains transmittance at 380 through 780 nm of 99.5% or more of transmittance thereof before coating the photosensitive coloring composition.
