Description

Display panel and electronic apparatus including the same The present invention relates to a display panel and an electronic device including the same, and more specifically, to a display panel including an encapsulation layer covering a light-emitting element and an electronic device including the same. The electronic device includes an active area that is activated according to an electrical signal. The electronic device can detect externally applied pressure through the active area and simultaneously display various images to provide information to the user. Meanwhile, electronic devices may include light-emitting elements using organic light-emitting materials or quantum dot light-emitting materials. These light-emitting elements are highly susceptible to oxygen and moisture, and various defects may occur if oxygen and moisture penetrate from the outside. Accordingly, development is underway regarding encapsulation layers to protect light-emitting elements. FIG. 1 is a combined perspective view of an electronic device according to one embodiment of the present invention. FIG. 2 is an exploded perspective view of an electronic device according to one embodiment of the present invention. FIG. 3 is a cross-sectional view of an electronic device according to one embodiment of the present invention. FIG. 4 is a cross-sectional view of an electronic device according to one embodiment of the present invention. FIG. 5 is a cross-sectional view of a part of an electronic device according to one embodiment of the present invention. FIG. 6 is a cross-sectional view of a part of an electronic device according to one embodiment of the present invention. FIG. 7 is a cross-sectional view of a part of a display module according to one embodiment of the present invention. The present invention is capable of various modifications and may take various forms, and specific embodiments are illustrated in the drawings and described in detail in the text. However, this is not intended to limit the invention to the specific disclosed forms, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. In this specification, where a component (or region, layer, part, etc.) is described as being "on," "connected," or "combined" with another component, it means that it may be directly placed/connected/combined with the other component, or that a third component may be placed between them. Meanwhile, in the present application, "direct placement" may mean that there are no additional layers, films, regions, plates, etc. added between a part such as a layer, film, region, or plate and another part. For example, "direct placement" may mean that two layers or two members are placed without using additional members such as adhesive members between them. Identical reference numerals denote identical components. Additionally, in the drawings, the thicknesses, proportions, and dimensions of the components are exaggerated for the effective illustration of the technical content. "And/or" includes all one or more combinations that the associated components can define. Terms such as "first," "second," etc., may be used to describe various components, but said components should not be limited by said terms. These terms are used solely for the purpose of distinguishing one component from other components. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component. A singular expression includes a plural expression unless the context clearly indicates otherwise. Additionally, terms such as "below," "lower side," "above," and "upper side" are used to describe the relationships between components illustrated in the drawings. These terms are relative concepts and are described based on the directions indicated in the drawings. In this specification, "placed on" may refer to a case where a component is placed not only on the upper side but also on the lower side. Terms such as "include" or "have" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Furthermore, terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an overly ideal or overly formal sense unless explicitly defined herein.
