The present disclosure relates to an organic electroluminescent device comprising a first electrode, a second electrode, and at least one organic layer interposed between the first electrode and the second electrode, wherein the organic layer comprises a light-emitting layer and a hole transport zone. By comprising a deuterated compound in at least one of the light-emitting layer and the hole transport zone, it is possible to provide an organic electroluminescent device having improved driving voltage, luminous efficiency, power efficiency, and/or lifetime properties.

Organic electroluminescent device

An organic light emitting diode and an organic light emitting device including the same are discussed. The organic light emitting diode can include a first electrode, a second electrode facing the first electrode, and a first emitting part including a green emitting material layer and positioned between the first and second electrodes. The green emitting material layer can include a first host, a second host and a dopant, wherein at least one of the first host and the second host is deuterated.

Organic light emitting diode and organic light emitting device including the same

The present disclosure relates to a plurality of light-emitting materials comprising at least one of first compounds and at least one of second compounds, wherein the first compound is represented by formula 1, and the second compound is represented by formula 2, and an organic electroluminescent device having improved lifetime properties can be provided by comprising the plurality of light-emitting materials.

Plurality of light-emitting materials and organic electroluminescent device comprising the same

The present disclosure relates to a plurality of light-emitting materials, an organic electroluminescent compound, and an organic electroluminescent device comprising the same. By comprising the organic electroluminescent compound or a specific combination of compounds according to the present disclosure as a host material and/or a dopant material, it is possible to provide an organic electroluminescent device having improved driving voltage, luminous efficiency and/or lifetime properties compared to conventional organic electroluminescent devices.
