[0117] In one or more embodiments, the amine-containing compound represented by Formula 1 may be one of Compounds 1 to 182 (eg, one selected from Compounds 1 to 182); however, embodiments of the present disclosure are not limited thereto:
[0118]
[0119]
[0120]
[0121]
[0122]
[0123]
[0124]

[0131] The amine-containing compound represented by Formula 1 may satisfy the following conditions: The structure in which a group represented by, a carbazolyl group, a fluorenyl group, a dibenzofuranyl group or a dibenzothiophene group is introduced into the diamine can improve the charge transport characteristics of the amine-containing compound by such a structure. Therefore, the exciton generation efficiency in the emission layer can be improved.
[0132] Although not limited by a particular theory, when the amine-containing compound of the present disclosure (such as the examples of the present disclosure) is used in a hole transport layer, the substituents may be changed differently between the first electrode and the second electrode, which causes one or more suitable changes in the highest occupied molecular orbital (HOMO) energy level. Therefore, when the amine-containing compound of the present disclosure (such as the examples of the present disclosure) is used in a hole transport layer, the exciton generation efficiency in the emission layer may be improved by differently changing the hole injection barrier of the hole transport layer.
[0133] The amine-containing compounds of the present disclosure (such as the examples of the present disclosure) can widen the band gap by adopting a structure in which two amines are connected to each other, and because the amine-containing compounds have tricyclic groups, such as fluorenyl, carbazole, etc., polarons can be stabilized to provide a long life of the light-emitting device. In addition, the increased charge jump rate can improve the charge mobility. In addition, by introducing a substituent into the naphthyl group, the color coordinates can be improved to emit deep blue light, and the structural stability of the compound can be ensured. By applying this to the emission layer of the light-emitting device, the luminous efficiency and device life can be improved.
[0134] Therefore, when the amine-containing compound represented by Formula 1 is applied to an organic light-emitting device, the device efficiency, driving voltage and life characteristics can be significantly improved. For example, by including the amine-containing compound represented by Formula 1 in the hole transport layer, an organic light-emitting device with high efficiency, low driving voltage and long life can be realized.

[0377] quantum dots
[0378] In one or more embodiments, the emission layer may include quantum dots.
[0379] The term "quantum dot" as used herein refers to a crystal of a semiconductor compound, and may include any material capable of emitting light at one or more suitable emission wavelengths depending on the size of the crystal.
[0380] The diameter of the quantum dot can be, for example, in the range of about 1 nm to about 10 nm. In the present disclosure, when a point, a plurality of points or a point particle is spherical, "diameter" indicates the particle diameter or the average particle diameter, and when the particle is non-spherical, "diameter" indicates the major axis length or the average major axis length. The diameter of the particle can be measured using a scanning electron microscope or a particle size analyzer. As a particle size analyzer, for example, HORIBA's LA-950 laser particle size analyzer can be used. When the size of the particle is measured using a particle size analyzer, the average particle diameter is referred to as D50. D50 refers to the average diameter of the particles whose cumulative volume corresponds to 50 vol% in the particle size distribution (e.g., cumulative distribution), and refers to the value of the particle size corresponding to 50% from the smallest particle when the total number of particles is 100% in the distribution curve accumulated in the order of the smallest particle size to the largest particle size.
[0381] Quantum dots can be synthesized by a wet chemical process, a metal organic chemical vapor deposition process, a molecular beam epitaxy process, or any process similar thereto.
[0382] The wet chemical process is a method that includes mixing the precursor material of the quantum dot with an organic solvent and then growing the quantum dot particle crystal. When the crystal grows, the organic solvent naturally acts as a dispersant coordinated on the surface of the quantum dot crystal and controls the growth of the crystal, so that the growth of the quantum dot particles can be controlled or selected by a process that is less expensive and easier than vapor deposition methods such as metal organic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE).
[0383] Quantum dots may include Group II-VI semiconductor compounds, Group III-V semiconductor compounds, Group III-VI semiconductor compounds, Group I-III-VI semiconductor compounds, Group IV-VI semiconductor compounds, Group IV elements or compounds, or any combination thereof.

[0389] The Group IV elements or compounds may include: single elements, such as Si or Ge; binary compounds, such as SiC or SiGe; or any combination thereof.
[0390] Each element included in the multi-element compound such as the binary compound, the ternary compound, and the quaternary compound may be present in the particle at a substantially uniform concentration or a non-substantially uniform concentration.
[0391] In some embodiments, the quantum dot may have a single structure in which the concentration of each element in the quantum dot is substantially uniform or a core-shell dual structure. For example, the material included in the core and the material included in the shell may be different from each other.
[0392] The shell of a quantum dot can act as a protective layer to prevent chemical degradation of the core to maintain semiconductor properties, and / or act as a charging layer to impart electrophoretic properties to the quantum dot. The shell can be a single layer or multiple layers. The interface between the core and the shell can have a concentration gradient, where the concentration of the element present in the shell decreases toward the center of the core.
[0393] Examples of the shell of a quantum dot may be an oxide of a metal, a metalloid or a non-metal, a semiconductor compound, or any combination thereof. Non-limiting examples of an oxide of a metal, a metalloid or a non-metal may be: a binary compound such as SiO 2 、Al 2 O 3 、TiO 2 、ZnO、MnO、Mn 2 O 3 , Mn 3 O4 , CuO, FeO, Fe 2 O 3 , Fe 3 O 4 , CoO, Co 3 O 4 and / or NiO; ternary compounds such as MgAl 2 O 4 、CoFe 2 O 4 、NiFe 2 O 4 and / or CoMn 2 O 4 ; and any combination thereof.

[0394] The full width at half maximum (FWHM) of the emission spectrum of the quantum dot can be about 45nm or less, such as about 40nm or less, such as about 30nm or less, and within these ranges, the color purity or color reproducibility of the quantum dot can be improved. In some embodiments, because the light emitted by the quantum dot is emitted in all directions, the wide viewing angle can be improved.
[0395] In one or more embodiments, the quantum dots may be in the form of spherical nanoparticles, pyramidal nanoparticles, multi-armed nanoparticles, cubic nanoparticles, nanotubes, nanowires, nanofibers, or nanoplates.
[0396] Because the energy band gap of quantum dots can be adjusted by controlling the size of quantum dots, light having one or more suitable wavelength bands can be obtained from the quantum dot emission layer. Therefore, by utilizing quantum dots of different sizes, an organic light-emitting device that emits light of one or more suitable wavelengths can be realized. In one or more embodiments, the size of the quantum dots can be selected so that the quantum dots can emit red light, green light, and / or blue light. In some embodiments, quantum dots having a suitable size can be configured to emit white light through a combination of one or more suitable colors of light.
