Provided are a heterocyclic compound represented by Formula 1-1 or 1-2, an organic light-emitting device including the heterocyclic compound, and an electronic apparatus including the organic light-emitting device: Formulae 1-1 and 1-2 may each be understood by referring to the descriptions of Formulae 1-1 and 1-2 provided herein.

Heterocyclic compound, organic light-emitting device including heterocyclic compound, and electronic apparatus including organic light-emitting device

Provided is an organic light-emitting device including an emission layer including a first compound, a second compound, a third compound, and a fourth compound, each satisfying a certain condition.

Organic light-emitting device

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.

Delayed fluorescence material and organic light emitting device having the delayed fluorescence material

An organometallic compound including a first electrode, a second electrode, and an organic layer disposed between the first electrode and the second electrode, wherein the organic layer includes an emission layer, and wherein the organic layer further includes a first material represented by Formula 1 and a second material represented by Formula 2: wherein in Formulae 1 and 2, groups and variables are the same as described in the specification.
