Abstract
There is provided an ink composition that can form a color filter pixel unit with high external quantum efficiency. An ink composition containing light-emitting nanocrystal particles, light-diffusing particles, and at least two monomers with an ethylenically unsaturated group, wherein the at least two monomers include two monomers with Hansen solubility parameters δd, δp, and δh that satisfy the following conditions: 16.0 MPa0.5≤δd<18.0 MPa0.5; 2.5 MPa0.5≤δp<5.5 MPa0.5; 2.5 MPa0.5≤δh<8.0 MPa0.5.
