Abstract: A colored resin composition containing an alkali-soluble resin (A), a colorant (B), an organic solvent (C), and a photosensitizer (D), the colored resin composition containing at least a zirconia compound particle as the colorant (B), wherein the zirconia compound particle contains zirconium nitride having a crystallite size of 10 nm or more and 60 nm or less, and the crystallite size is determined from a half width of a peak derived from a (111) plane in an X-ray diffraction spectrum using a CuKα ray as an X-ray source. The present invention provides a highly sensitive colored resin composition by improving light transmissivity in the ultraviolet region (wavelength 365 nm) generally used in photolithography and by improving a light shielding property in the visible region.

Abstract: A black resin composition is provided that presents an achromatic reflected color tone, has a high visible-light-blocking ability and a high near-infrared penetrability, and exhibits a smaller amount of transmitted scattered light, where the black resin composition includes (A) a resin, (B) a colorant, and (C) an organic solvent, wherein the black composition includes a red pigment and a blue pigment as (B) the colorant, wherein amount of the red pigment is 20 to 80 wt % with respect to the total amount of (B) the colorant, and wherein crystalline size of the red pigment in a colored film composed of a cured product of the black resin composition is 5 nm or more and 25 nm or less, as calculated from a half bandwidth determined from a main peak of an X-ray diffraction spectrum obtained using CuKα rays as an X-ray source.
