A delayed fluorescence material is disclosed. The delayed fluorescence material has a molecular structure that includes an electron donor unit that donates electrons; and an electron acceptor unit that is coupled to the electron donor unit and accepts electrons, wherein the electron acceptor unit includes an indolocarbazole group having at least one acceptor functional-group bound to the indolocarbazole group. Thus, the delayed fluorescence material exhibits high structural and thermal stability as well as high quantum efficiency.
