Like reference numerals refer to like elements throughout.

In order to clearly express various layers and regions in the drawings, the thicknesses are enlarged. Throughout the specification, like reference numerals are assigned to similar parts. When a part of a layer, film, region, plate, etc. is said to be “on” another part, it includes not only cases where it is “directly on” another part, but also cases where there is another part in between. Conversely, when we say that a part is "just above" another part, we mean that there is no other part in the middle. Also, when a part of a layer, film, region, plate, etc. is said to be “under” another part, it includes not only the case where the other part is “directly under” but also the case where there is another part in the middle.

Spatially relative terms "below", "beneath", "lower", "above", "upper", etc. It can be used to easily describe a correlation between an element or components and other elements or components. The spatially relative terms should be understood as terms including different orientations of the device during use or operation in addition to the orientation shown in the drawings. For example, when an element shown in the figures is turned over, an element described as "beneath" or "beneath" another element may be placed "above" the other element. Accordingly, the exemplary term “below” may include both directions below and above. The device may also be oriented in other orientations, and thus spatially relative terms may be interpreted according to orientation.

In the present specification, when a part is said to be connected to another part, it includes not only a case in which it is directly connected, but also a case in which it is electrically connected with another element interposed therebetween. In addition, when it is said that a part includes a certain component, this means that other components may be further included, rather than excluding other components, unless otherwise stated.

In this specification, terms such as first, second, third, etc. may be used to describe various components, but these components are not limited by the terms. The above terms are used for the purpose of distinguishing one component from other components. For example, without departing from the scope of the present invention, a first component may be referred to as a second or third component, and similarly, the second or third component may be alternately named.

Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used with the meaning commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, terms defined in a commonly used dictionary are not to be interpreted ideally or excessively unless clearly defined in particular.
