[0057] Here, some embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. The terms or words used in this specification and claims should not be interpreted as limited to the ordinary meaning or dictionary meaning, and should be interpreted as meanings and concepts consistent with the technical ideas of the present disclosure based on the principle that the inventor can be his / her own lexicon compiler to appropriately define the concept of the term.

[0058] The embodiments described in this specification and the configurations shown in the accompanying drawings are provided as some example embodiments of the present disclosure and do not necessarily represent all technical ideas, aspects and features of the present disclosure. Therefore, it will be understood that when submitting this application, there may be various equivalents and modifications that can replace or modify the embodiments described herein.

[0059] It will be understood that when an element or layer is referred to as being "on," "connected to," or "bound to" another element or layer, it may be directly on, directly connected to, or directly bound to the other element or layer, or there may be one or more intervening elements or layers. When an element or layer is referred to as being "directly on," "directly connected to," or "directly bound to" another element or layer, there may be no intervening elements or layers. For example, when a first element is described as being "bound to" or "connected to" a second element, the first element may be directly bound or connected to the second element, or the first element may be indirectly bound or connected to the second element via one or more intervening elements.

[0060] In the accompanying drawings, for the clarity of the illustration, the sizes of various elements, layers, etc. may be exaggerated. The same reference numerals represent the same or similar elements. As used herein, the term "and / or" includes any and all combinations of one or more related listed items. In addition, when describing the embodiments of the present disclosure, the use of "may" relates to "one or more embodiments of the present disclosure". When after the element list, expressions such as "at least one of" and "any one of" modify the entire element list without modifying the individual elements of the list. When phrases such as "at least one of A, B and C", "at least one of A, B or C", "at least one of the groups selected from A, B and C" or "at least one selected from A, B and C" are used to represent the list of elements A, B and C, the phrase may refer to any and all suitable combinations or subsets of A, B and C, such as A, B, C, A and B, A and C, B and C, or A and B and C. As used herein, the terms "use", "use of ..." and "used" may be considered to be synonymous with the terms "utilize", "utilize ..." and "utilize", respectively. As used herein, the terms "substantially," "about," and similar terms are used as terms of approximation rather than terms of degree, and are intended to take into account the inherent variations in measurements or calculations that those of ordinary skill in the art would recognize.

[0061] It will be understood that although the terms "first," "second," "third," etc., may be used herein to describe various elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or section from another element, component, region, layer, or section. Thus, a first element, component, region, layer, or section discussed below may be referred to as a second element, component, region, layer, or section without departing from the teachings of the example embodiments.

[0062] For ease of description, spatial relationship terms such as "under", "below", "below", "above", "on", etc. may be used here to describe the relationship of an element or feature to another element or feature as shown in the figure. It will be understood that in addition to the orientations depicted in the figures, the spatial relationship terms are also intended to cover different orientations of the device in use or operation. For example, if the device in the accompanying drawings is turned over, the elements described as "under" or "below" other elements or features will be oriented to be "above" or "on" the other elements or features. Therefore, the term "under" can cover both above and below orientations. The device can be oriented otherwise (e.g., rotated 90 degrees or in other orientations), and the spatial relationship descriptors used here should be interpreted accordingly.

[0063] The terms used herein are for the purpose of describing the embodiments of the present disclosure, and are not intended to be limitations of the present disclosure. As used herein, the singular form "a" is also intended to include the plural form, unless the context clearly states otherwise. It will also be understood that when used in this specification, the terms "include", "includes ...", "includes" and / or "includes ..." indicate the existence of stated features, wholes, steps, operations, elements and / or parts, but do not exclude the existence or addition of one or more other features, wholes, steps, operations, elements, parts and / or their groups.

[0064] In addition, any numerical range disclosed and / or described herein is intended to include all sub-ranges of the same numerical precision contained in the described range. For example, the range of "1.0 to 10.0" is intended to include all sub-ranges between the described minimum value 1.0 and the described maximum value 10.0 (and including the described minimum value 1.0 and the described maximum value 10.0), that is, all sub-ranges with a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as, for example, 2.4 to 7.6. Any maximum numerical limit described here is intended to include all lower numerical limits contained therein, and any minimum numerical limit described in this specification is intended to include all higher numerical limits contained therein. Therefore, the applicant reserves the right to modify this specification (including claims) to explicitly describe any sub-range contained in the scope explicitly described here.

[0065] Referring to two compared elements, features, etc. as "the same" may mean that they are the same or substantially the same. Thus, the phrases "the same" or "substantially the same" may include situations with deviations that are considered low in the art (e.g., 5% or less). In addition, when a parameter is referred to as being uniform in a given area, it may mean that it is uniform in terms of average value.

[0066] Throughout the specification, unless otherwise specified, each element may be in the singular or in the plural.

[0067] When any element is referred to as being disposed (or placed or positioned) "on (or below)" or "on (or below)" a component, it may mean that the arbitrary element is placed in contact with the upper (or lower) surface of the component, and may also mean that another component may be interposed between the component and any arbitrary element disposed (or placed or positioned) on (or below) the component.

[0068] Furthermore, it will be understood that when an element is referred to as being "coupled," "linked," or "connected" to another element, the elements may be directly "coupled," "linked," or "connected" to each other, or there may be one or more intervening elements therebetween through which the element may be "coupled," "linked," or "connected" to the other element. Furthermore, when a portion is referred to as being "electrically coupled" to another portion, the portion may be directly electrically connected to the other portion, or there may be one or more intervening portions therebetween such that the portion and the other portion are indirectly electrically connected to each other.

[0069] Throughout the specification, when "A and / or B" is stated, it means A, B, or A and B, unless otherwise specified. That is, "and / or" includes any or all combinations of the listed multiple items. When "C to D" is stated, it means C or greater and D or less, unless otherwise specified.
