Object A problem to be solved by the present invention is to provide a luminescent nanocrystal complex that tends to disperse orderly in a polymer matrix and is superior in dispersibility in structurally mesogenic crosslinkable polymer matrices. Solution The present invention is a luminescent nanocrystal complex that contains luminescent nanocrystals and a surface-modifying compound that modifies the surface of the luminescent nanocrystals. The surface-modifying compound has a mesogenic backbone and a group that binds to the surface of the luminescent nanocrystals.
