摘要

PURPOSE: A manufacturing method of a micro capsule type quantum dot-polymer is provided to provide a quantum dot-polymer composite having excellent quantum dot dispersity and capable of stably maintaining quantum efficiency for long term. CONSTITUTION: A manufacturing method of a micro capsule type quantum dot-polymer comprises a step of forming a polymer solution by heating a first polymer having a polar functional group in a side chain and a second polymer with a higher molecular weight than that of the first polymer, in a first solvent (S13); a step of forming a mixture by adding a quantum dot dispersion in which quantum dots capped by a capping layer in a second solvent into the polymer solution(S17); and a step of forming a quantum dot-polymer composite in which the quantum dots are dispersed in a polymer matrix by cooling the mixture (S19).
