Abstract

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.
