Abstract
A QD protecting material having high compatibility with a binder component in a luminescent layer. The luminescent layer contains, as a part of its chemical structure, a compound containing a moiety A having a sum atomic weight MA of 100 or more and quantum dots protected by a protecting material, the protecting material contains, as a part of its chemical structure, a linking group connected to a quantum dot surface and a moiety B that has a sum atomic weight MB of 100 or more, satisfies a relationship between MB and MA represented by |MA−MB|/MB (2, and satisfies the requirement that the sum atomic weight MB is larger than one-third of the molecular weight of the protecting material, and a solubility parameter SA of the moiety A and a solubility parameter SB of the moiety B satisfy a relationship represented by |SA (SB| (2.
