In the following embodiments, when various components such as layers, films, regions, and plates are described as being "on" another component, this includes not only cases where they are "directly on" another component, but also cases where other components are interposed between them. Furthermore, for convenience of explanation, the size of components in the drawings may be exaggerated or reduced. For example, the size and thickness of each component shown in the drawings are depicted arbitrarily for convenience of explanation, and therefore the present invention is not necessarily limited to what is illustrated. In the following embodiments, the x-axis, y-axis, and z-axis are not limited to three axes in an orthogonal coordinate system and can be interpreted in a broader sense that includes them. For example, the x-axis, y-axis, and z-axis may be orthogonal to each other, but they may also refer to different directions that are not orthogonal to each other. In the following examples, terms such as first, second, etc. are used not in a limiting sense, but for the purpose of distinguishing one component from another component. In the following embodiments, terms such as "comprising" or "having" mean that the features or components described in the specification are present, and do not preclude the possibility that one or more other features or components may be added. In this specification, "A and/or B" indicates the case where it is A, B, or both A and B. And, "at least one of A and B" indicates the case where it is A, B, or both A and B. In the following embodiments, when it is stated that a membrane, region, or component, etc. is connected, it includes not only cases where the membrane, region, or component is directly connected, but also cases where other membranes, regions, or components are interposed between them to form an indirect connection. For example, when it is stated in this specification that a membrane, region, or component, etc. is electrically connected, it includes not only cases where the membrane, region, or component, etc. are directly electrically connected, but also cases where other membranes, regions, or components are interposed between them to form an indirect electrical connection.
