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.
