[0001] Cross-reference with related applications

[0002] This application claims priority based on Korean Patent Application No. 10-2020-0136282 dated October 20, 2020 and Korean Patent Application No. 10-2021-0139317 dated October 19, 2021, the entire contents of which are disclosed in the documents of the Korean patent applications and are incorporated in this specification.

[0003] This invention relates to organic light-emitting devices. Background Technology

[0004] Organic light emission typically refers to the phenomenon of converting electrical energy into light energy using organic materials. Organic light-emitting devices (OLEDs) utilizing organic light emission exhibit wide viewing angles, excellent contrast ratios, fast response times, and superior brightness, driving voltage, and response speed characteristics, thus attracting extensive research.

[0005] Organic light-emitting devices (OLEDs) typically have a structure comprising an anode and a cathode, and an organic layer located between the anode and cathode. To improve the efficiency and stability of OLEDs, the organic layer is often formed by a multilayer structure composed of different materials, such as a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, and an electron injection layer. In such an OLED structure, if a voltage is applied between the two electrodes, holes are injected into the organic layer from the anode, and electrons are injected into the organic layer from the cathode. When the injected holes and electrons meet, they form excitons, which emit light when they re-enter the ground state.

[0006] For organic materials used in organic light-emitting devices as described above, there is a continuous need to develop new materials.

[0461] As shown in Tables 1 to 5 above, the organic light-emitting devices of the embodiments that use both the first compound represented by Chemical Formula 1 and the second compound represented by Chemical Formula 2 as the host material of the light-emitting layer exhibit superior driving voltage, luminous efficiency, and lifetime characteristics compared to the organic light-emitting devices of the comparative examples that use only one of the compounds represented by Chemical Formulas 1 and 2, or neither of them.

This confirms that when the combination of the first compound represented by Chemical Formula 1 and the second compound represented by Chemical Formula 2 is used as a common host, energy transfer to the red dopant is effectively achieved within the red emitting layer. It can be determined that this is because the first compound has high stability for electrons and holes, and furthermore, it is determined that due to the simultaneous use of the second compound, while the amount of holes increases, a more stable balance between electrons and holes is maintained within the red emitting layer.
