Abstract
A composition for manufacturing an organic electronic device includes at least three organic functional materials H1, H2, and H3, and at least one organic solvent. The organic functional materials H1 and H2 can form a type II semiconductor heterojunction structure. A LUMO value of the organic functional material H3 is greater than or equal to that of the organic functional materials H1 and H2, and a HOMO value thereof is less than or equal to that of the organic functional materials H1 and H2.
