Black matrix composition, black matrix, and black matrix production method

A composition for a black matrix comprising:

• (I) a black colorant comprising carbon black having a volume average particle diameter of 1 to 300 nm;
• (II) a siloxane polymer having repeating units represented by the general formulae (Ia), (Ib) and/or (Ic)
• (wherein
• R1 is a linear, branched or cyclic, alkyl group or alkenyl group having 1 to 10 carbon atoms or an aryl group having 6 to 20 carbon atoms, where one or more methylene may be replaced by oxygen, or one or more hydrogen may be replaced by fluorine,
• the ratio x of the general formula (Ia) in all of the repeating units is 0 mol % or more and 30 mol % or less, the ratio y of the general formula (Ib) in all of the repeating units is 50 mol % or more and 100 mol % or less, and the ratio z of the general formula (Ic) in all of the repeating units is 0 mol % or more and 30 mol % or less);
• (III) surface modified silica fine particles having, on at least a part of the surface, a functional group represented by the general formula (3):
• —(O)kSiR3m(OR5)l (3)
• (wherein
• R3 represents a linear, branched or cyclic, alkyl group or alkenyl group having 1 to 20 carbon atoms or an aryl group having 6 to 20 carbon atoms, where one or more methylene may be replaced by oxygen, or one or more hydrogen may be replaced by fluorine
• R5 represents hydrogen or an alkyl group having 1 to 10 carbon atoms,
• k+1+m=4, k=1 to 3, and m=0 to 3)
• and having a volume average particle diameter of 1 to 300 nm;
• (IV) a thermal base generator;
• and
• (V) a solvent.
