1. A light-emitting device, comprising:
a substrate;
an anode;
a cathode; and
an emissive layer between the anode and the cathode, the emissive layer comprising quantum dots having ligands, a cross-linked matrix comprising a cross-linkable charge transport material other than the ligands, and another charge transport material,
wherein:
the quantum dots are dispersed in the cross-linked matrix,
the another charge transport material alters mobility of charge carriers of the emissive layer,
the cross-linkable charge transport material is a cross-linkable hole transporting material,
the another charge transport material is an efficient hole transporting material that improves hole mobility more than the cross-linkable charge transport material, and
in the emissive layer, the quantum dots and the another charge transport material are layer-separated from each other such that the quantum dots are close to the cathode and the another charge transport material is close to the anode.
