A curable composition containing semiconductor nanoparticles, which comprises silica microparticles (a), a (meth)acrylate compound (B), a polymerization initiator (d) and semiconductor nanoparticles (e) that serve as a light emitter, wherein the (meth)acrylate compound (B) comprises at least two compounds selected from the group consisting of a bifunctional (meth)acrylate compound (h) having two (meth)acryloyloxy groups, a polyfunctional (meth)acrylate compound (b) having at least three (meth)acryloyloxy groups and a monofunctional (meth)acrylate compound (c) having one (meth)acryloyloxy group, and the surface of each of the silica microparticles (a) is treated with a silane compound (f) represented by general formula (1) and a silane compound (g) represented by general formula (2).n(In formula (1), R 1 represents a hydrogen atom or a methyl group; R 2 represents an alkyl group having 1 to 3 carbon atoms or a phenyl group; R 3 represents a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms; q represents an integer of 1 to 16; and r represents an integer of 0 to 2. In formula (2), R 4 represents an alkyl group having 1 to 3 carbon atoms or a phenyl group; R 5 represents a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms; s represents an integer of 0 to 6; and t represents an integer of 0 to 2.) |
