Dispersion composition, polymerizable composition, light-shielding color filter, solid-state image pick-up element, liquid crystal display device, wafer level lens, and image pick-up unit

A dispersion composition comprising:

• (A) titanium black;
• (B) a graft copolymer;
• and (C) a solvent,
• wherein the graft copolymer comprises at least a structural unit represented by any one of the following Formula (1) to Formula (5):
• wherein, in Formula (1) to Formula (5), X1, X2, X3, X4, X5, and X6 each independently represents a hydrogen atom or a monovalent organic group;
• Y1, Y2, Y3, Y4, and Y5 each independently represents a divalent linking group;
• Z1, Z2, Z3, Z4, and Z5 each independently represents a hydrogen atom or a monovalent organic group;
• R represents a hydrogen atom or a monovalent organic group;
• R's having different structures from one another may be present in the copolymer;
• and n, m, p, q, and r each independently represents an integer of from 1 to 500;
• and
• the divalent linking group represented by Y1, Y2, Y3, Y4 or Y5 is any one selected from the following linking groups (Y-1) to (Y-20):
• wherein, in (Y-1) to (Y-20), A represents a bond to a left terminal end group in any of Formula (1) to Formula (5), and B represents a bond to a right terminal end group in any of Formula (1) to Formula (5).
