Hereinafter, the present invention will be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the present invention are shown. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Throughout the specification, the same reference numerals denote the same elements. It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected" to another element, it can be directly on or connected to the other element, or Intermediate elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. As used herein, "connected" may refer to physical and/or electrical connections. Furthermore, "electrical connection" or "coupling" can mean that there are other components between the two components.

In addition, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe the relationship between one element and another element, as shown. It should be understood that relative terms are intended to include different orientations of the device than those shown in the figures. For example, if the device in one drawing is turned over, the element described as being on the "lower" side of the other element will be oriented on the "upper" side of the other element. Thus, the exemplary term "lower" may include "lower" and "upper" orientations, depending on the particular orientation of the drawings. Similarly, if the device in one drawing is turned over, elements described as "below" or "beneath" other elements would then be oriented "above" the other elements. Thus, the exemplary terms "above" or "below" can include an orientation of above and below.

As used herein, "about", "approximately", or "substantially" includes the stated value and the average value within the acceptable deviation range of the specific value determined by those of ordinary skill in the art, taking into account the measurements and A certain amount of measurement-related errors (ie, measurement system limitations). For example, "about" may mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, ±5%. In addition, "about", "approximately" or "substantially" used in this article can select a more acceptable range of deviation or standard deviation according to optical properties, etching properties or other properties, instead of applying one standard deviation to all properties .

Exemplary embodiments are described herein with reference to cross-sectional views that are schematic diagrams of idealized embodiments. Therefore, a change in the shape of the graph as a result of, for example, manufacturing techniques and/or tolerances can be expected. Therefore, the embodiments described herein should not be construed as being limited to the specific shapes of the regions as shown herein, but include deviations in shapes caused by manufacturing, for example. For example, an area shown or described as flat may generally have rough and/or non-linear characteristics. In addition, the acute angle shown may be round. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the precise shapes of the regions, and are not intended to limit the scope of the claims.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this invention belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant technology and the present invention, and will not be interpreted as idealized or excessive Formal meaning unless explicitly defined as such in this article.

Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element symbols are used in the drawings and description to denote the same or similar parts.
