Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2019-0016836 filed on February 13, 2019, in the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0002] One or more embodiments of the present disclosure are directed to an organic light emitting device including an organic layer including a carbazole derivative compound. Background Art

[0003] Compared to other devices in the art, organic light emitting devices are self-emissive devices that have wide viewing angles, high contrast, short response times, and excellent characteristics in terms of brightness, driving voltage, and / or response speed, and can produce full-color images.

[0004] An example of such an organic light-emitting device may include a first electrode disposed (e.g., placed or positioned) on a substrate and a hole transport region, an emission layer, an electron transport region, and a second electrode sequentially disposed on the first electrode. Holes provided from the first electrode may move toward the emission layer through the hole transport region, and electrons provided from the second electrode may move toward the emission layer through the electron transport region. Carriers such as holes and electrons may then recombine in the emission layer to generate excitons. The excitons then transition from an excited state to a ground state, thereby generating light.

[0005] In the prior art, a phenylenediamine structure is disclosed as a hole injection material that can be used for an organic light-emitting device. As hole transport materials, aromatic diamine derivatives and / or aromatic condensed ring diamine derivatives are known. As improved (or derived) compounds from these compounds, arylamine compounds containing carbazole have been disclosed and used as hole transport materials. In addition, arylamine compounds having a carbazole group substituted at position 3 have been disclosed and used as hole injection materials.

[0006] However, since devices in which these compounds are used for a hole injection layer and / or a hole transport layer generally have insufficient luminous efficiency, improved luminous efficiency characteristics are required. Summary of the invention

[0007] One or more aspects of embodiments of the present disclosure relate to hole transport compounds having improved luminous efficiency characteristics compared to comparable compounds and organic light emitting devices including the hole transport compounds.

[0008] Additional embodiments will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the presented embodiments.
