Cross Reference to Related Applications
The present application claims priority and rights of korean patent application nos. 10-2022-0016967 and 10-2022-0063592, filed in the korean intellectual property office on day 2, 9, 2022 and day 5, 2022, 24, respectively, the entire contents of which are incorporated herein by reference.
Technical Field
The present disclosure relates to a light emitting device and an electronic apparatus including the same.
Background
Compared with the related art device, the light emitting device is a self-emission device, which has a wide viewing angle, high contrast, short response time, and excellent characteristics in terms of brightness, driving voltage, and response speed, and generates a multicolor image.
In the light emitting device, a first electrode is disposed on a substrate, and a hole transport region, an emission layer, an electron transport region, and a second electrode are sequentially formed on the first electrode. Holes supplied from the first electrode move toward the emission layer through the hole transport region, and electrons supplied from the second electrode move toward the emission layer through the electron transport region. Carriers, such as holes and electrons, recombine in the emissive layer to generate excitons. The excitons may transition from an excited state to a ground state, thereby generating light.

It will be understood that the above embodiments are described in a generic and descriptive sense only and not for purposes of limitation, and that the disclosure is not limited to the above embodiments.
Drawings
The above and other aspects and features of the present disclosure will become more apparent by describing in detail embodiments thereof with reference to the attached drawings in which:
fig. 1 is a schematic cross-sectional view of a light emitting device according to an embodiment;
FIG. 2 is a schematic cross-sectional view of an electronic device according to an embodiment; and is also provided with
Fig. 3 is a schematic cross-sectional view of an electronic device according to another embodiment.
Detailed Description
The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments are shown. This disclosure may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In the drawings, the size, thickness, proportions and dimensions of elements may be exaggerated for ease of description and for clarity. Like numbers refer to like elements throughout.
In the description, it will be understood that when an element (or region, layer, section, etc.) is referred to as being "on," "connected to" or "coupled to" another element (or region, layer, section, etc.), it can be directly on, connected to or coupled to the other element (or region, layer, section, etc.), or one or more intervening elements (or regions, layers, sections, etc.) may be present therebetween. In a similar sense, when an element (or region, layer, section, etc.) is referred to as "overlying" another element (or region, layer, section, etc.), it can directly overlie the other element (or region, layer, section, etc.), or one or more intervening elements (or regions, layers, sections, etc.) may be present therebetween.
In the description, when an element (or region, layer, section, etc.) is "directly on," "directly connected to" or "directly coupled to" another element (or region, layer, section, etc.), there are no intervening elements (or regions, layers, sections, etc.). For example, "directly on" … … can mean that two layers or elements (or regions, portions, etc.) are provided without additional elements (or regions, layers, portions, etc.) such as adhesive elements therebetween.
As used herein, the use of expressions in the singular form, such as "a", "an", and "the" are intended to include the plural form as well, unless the context clearly indicates otherwise.
As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. For example, "a and/or B" may be understood to mean "A, B or a and B". The terms "and" or "may be used in a connective or compartmental sense and are to be understood as being equivalent to" and/or ".
In the specification and claims, for the purposes of their meaning and explanation, at least one of the terms "… …" is intended to include a meaning of "at least one selected from the group consisting of … …". For example, "at least one of A, B and C" may be understood to mean "a only, B only, C only, or any combination of two or more of A, B and C, such as ABC, ACC, BC or CC". The term "at least one of … …" modifies the entire list of elements when before/after the list of elements, rather than modifying individual elements of the list.
It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Thus, a first element could be termed a second element without departing from the teachings of the present disclosure. Similarly, a second element may be termed a first element without departing from the scope of the present disclosure.
For ease of description, spatially relative terms "below," "under," "lower," "above," or "upper" and the like may be used herein to describe one element or component's relationship to another element or component as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, where a device illustrated in the figures is turned over, elements located "below" or "beneath" another device could be oriented "above" the other device. Accordingly, the illustrative term "below" may include both a lower position and an upper position. The device may also be oriented in other directions, and therefore spatially relative terms may be construed differently depending on the orientation.
The term "about" or "approximately" as used herein includes the recited values and means that the measurement in question and the errors associated with the recited number of measurements (i.e., limitations of the measurement system) are considered within the acceptable deviation of the recited values as determined by one of ordinary skill in the art. For example, "about" may mean within one or more standard deviations of the recited values, or within ±20%, ±10% or ±5% of the recited values.
It will be understood that the terms "comprises," "comprising," "includes," "including," "having," "includes," "including," "containing," "includes," "including," "containing," "including," "having," "containing," "including," etc. are intended to specify the presence of stated features, integers, steps, operations, elements, components, or any combination thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or groups thereof.
The term "interlayer" as used herein may refer to a single layer and/or multiple layers between a first electrode and a second electrode of a light emitting device.
Unless otherwise defined or implied herein, all terms (including technical and scientific terms) used have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
One aspect provides a light emitting device, which may include:
a first electrode;
a second electrode facing the first electrode;
an interlayer between the first electrode and the second electrode and comprising an emissive layer;

In an embodiment, the first compound; a second compound; and at least one of the third compound and the fourth compound may be included between the first electrode and the second electrode of the light emitting device. For example, a first compound; a second compound; and at least one of the third compound and the fourth compound may be included in an interlayer of the light emitting device.

In an embodiment, an emission layer of an interlayer in a light emitting device may include a dopant and a host. For example, the host may include an anthracene compound, but is not limited thereto, and the dopant may include a dopant containing C 8 -C 60 A compound of polycyclic groups in which at least two cyclic groups are fused while sharing boron (B). However, the embodiment is not limited thereto.
The amount of host may be greater than the amount of dopant. For example, the amount of dopant in the emissive layer may be in the range of about 0.01 parts by weight to about 5 parts by weight based on 100 parts by weight total of host and dopant.

For example, in an embodiment, the emissive layer may emit blue light having a maximum emission wavelength in the range of about 430nm to about 490 nm.
In an embodiment, the light emitting device may include a capping layer outside the first electrode or outside the second electrode.
For example, the light emitting device may further include at least one of a first capping layer outside the first electrode and a second capping layer outside the second electrode, and at least one of the first capping layer and the second capping layer may include at least one of a first compound to a fourth compound. The first capping layer and/or the second capping layer may each be the same as described herein.
In an embodiment, the light emitting device may further include:
a first capping layer outside the first electrode, and the first capping layer includes at least one of a first compound to a fourth compound;
a second capping layer outside the second electrode, and the second capping layer includes at least one of the first to fourth compounds; or (b)

The phrase "(interlayer and/or capping layer) as used herein includes a case where" the first compound represented by formula 1 "means" (interlayer and/or capping layer) may include one kind of "the first compound represented by formula 1" or a case where "(interlayer and/or capping layer) may include two or more different kinds of" the first compound represented by formula 1 ". The second compound to the fourth compound may each be explained in the same manner.
For example, the interlayer and/or the capping layer may include only compound 1 as an amine compound. Thus, the compound 1 may be included in a hole transport region of the light emitting device. For example, the interlayer may include both compound 1 and compound 2 as amine compounds. Compound 1 and compound 2 may be present in the same layer (e.g., both compound 1 and compound 2 may be present in the hole transport region), or may be present in different layers (e.g., compound 1 may be present in the emissive layer, and compound 2 may be present in the hole transport region).
Another aspect provides an electronic device that may include a light emitting apparatus. The electronic device may further include a thin film transistor.
For example, in an embodiment, the electronic device may further include a thin film transistor including a source electrode and a drain electrode, wherein the first electrode of the light emitting device may be electrically connected to the source electrode or the drain electrode.

The first compound to the fourth compound are each an amine compound and have a condensed ring structure in the molecule (see fluorenyl group and the like in formula 1; carbazolyl group and fluorenyl group and the like in formula 2; T in formula 3) 3 Etc.; t in formula 4 4 Etc.), the first to fourth compounds may have a high glass transition temperature (Tg) and/or a high melting point so that crystallization may be prevented. Among the first to fourth compounds, heat resistance to heat generated during light emission and high temperature resistance under a high temperature environment can be increased, resulting in excellent electrical stability and excellent charge transport ability.
Because the third compound includes cycloalkyl groups having high rigidity (R in formula 3 31 And R is 32 ) The third compound may have excellent optical properties. Since the fourth compound has high flatness of the entire molecule, the fourth compound may have excellent charge transporting property, and thus is also highly stable during charge transport.
Therefore, when the first to third compounds or the first to fourth compounds are used as a hole transporting material, an electronic device (e.g., an organic light emitting device) having characteristics of low driving voltage, high luminance, high light emitting efficiency, and long lifetime can be realized.

For example, the quantum dots may have a FWHM of the emission wavelength spectrum equal to or less than about 30 nm. When the FWHM of the quantum dot is within any of these ranges, the quantum dot may have improved color purity or color reproducibility.
