Description

Display device and electronic device including the same The present invention relates to a display device and an electronic device including the same. Generally, a display device includes a display module for displaying an image and a support member for supporting the display module. The display module includes a display panel for displaying an image, a window disposed on the display panel to protect the display panel from external scratches and impacts, and a protective layer disposed below the display panel to protect the display panel from external impacts. With the recent advancement of display technology, flexible display devices that can be transformed into various forms are being developed. Flexible display devices include flexible display modules that can be folded or rolled up. As flexible display devices are developed, there is a need for the development of technology that can improve the visibility of the display device even after folding.

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. Identical reference numerals denote identical components. Additionally, in the drawings, the thicknesses, proportions, and dimensions of components are exaggerated for the effective illustration of the technical content. "And/or" includes all one or more combinations that the associated components may 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 another. 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 the components depicted in the drawings. These terms are relative concepts and are described based on the directions indicated in the drawings. 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 rel
