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 CuK&#x3b1; 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.

Disclosed is a black resin composition with which a black matrix having high insulation properties even after heat treatment at a high temperature and, in addition, achromatic reflection properties can be readily formed. The black resin composition comprises (A) a light-shielding material, (B) an alkali-soluble resin, and (C) an organic solvent, and comprises (A-1) a carbon black and (A-2) titanium nitride compound particles as the light-shielding material (A). The carbon black (A-1) is surface-treated with a sulfur-containing compound, and in the surface composition, the percentage of carbon atoms is 95% or less and the percentage of sulfur atoms is 0.5% or more.
