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

The present disclosure relates to an organic electroluminescent compound, and an organic electroluminescent device comprising the same. By comprising the organic electroluminescent compound of the present disclosure, it is possible to provide an organic electroluminescent device having improved driving voltage, lifetime properties, and/or power efficiency.

Organic electroluminescent compound and organic electroluminescent device comprising the same

The present disclosure relates to an organic electroluminescent compound represented by formula 1, a plurality of host materials comprising a combination of specific compounds, and an organic electroluminescent device comprising the same. The organic electroluminescent device having improved driving voltage, luminous efficiency and/or lifespan properties can be provided by including the organic electroluminescent compound or a specific combination of compounds according to the present disclosure as a host material(s).

Organic electroluminescent compound, a plurality of host materials and organic electroluminescent device comprising 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 an organic electroluminescent compound and an organic electroluminescent device comprising the same. By comprising the organic electroluminescent compound, an organic electroluminescent device having a low driving voltage and/or a high luminous efficiency and/or a long lifespan can be provided.

The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. By comprising the compound according to the present disclosure, it is possible to produce an organic electroluminescent device having improved driving voltage, power efficiency, and/or lifetime properties compared to the conventional organic electroluminescent devices.

The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. The organic electroluminescent device having improved driving voltage and/or current efficiency characteristics can be provided by comprising the organic electroluminescent compound according to the present disclosure.

The present disclosure relates to an organic electroluminescent device comprising a light-emitting layer and a hole transport zone. By comprising a specific combination of a light-emitting layer and a hole transport zone, it is possible to provide an organic electroluminescent device having low driving voltage, high luminous efficiency and/or long lifespan properties.

The present disclosure relates to an organic electroluminescent device comprising an organic electroluminescent compound of high refractive index. According to the present disclosure, an organic electroluminescent device having decreased thickness while implementing a desired color coordinate, or implementing deeper color coordinate in the same device thickness can be provided. As such, the production efficiency of the device can be increased by decreasing the material amount used in the organic electroluminescent device or a broader light-emitting zone can be obtained due to deeper color characteristic in the same device thickness.
