Description

Windows and display device including the same The present invention relates to a window and a display device including the same, and more specifically, to a window with excellent mechanical properties and a display device including the same. Display devices are used in various multimedia devices, such as televisions, mobile phones, tablet computers, and game consoles, to provide visual information to users. Recently, various types of flexible display devices capable of folding or bending are being developed. Flexible display devices have the characteristic of being easy to carry because their shape can be changed in various ways, such as by folding, rolling, or bending. A flexible display device may include a foldable or bendable display panel and a window. However, the window of the flexible display device has a problem of being deformed by folding or bending movements or easily damaged by external impact. FIG. 1a is a perspective view showing the unfolded state of a display device according to one embodiment of the present invention. FIG. 1b is a perspective view showing the in-folding process of the display device illustrated in FIG. 1a. FIG. 1c is a perspective view showing the out-folding process of the display device illustrated in FIG. 1a. FIG. 2a is a perspective view showing the unfolded state of a display device according to one embodiment of the present invention. FIG. 2b is a perspective view showing the in-folding process of the display device illustrated in FIG. 2a. FIG. 2c is a perspective view showing the out-folding process of the display device illustrated in FIG. 2a. FIG. 3 is an exploded perspective view of a display device according to one embodiment of the present invention. FIG. 4 is a cross-sectional view of a display device according to one embodiment of the present invention. FIG. 5 is a cross-sectional view of a display module according to one embodiment of the present invention. FIGS. 6a to 6c are cross-sectional views showing part of the configuration of a display device according to one embodiment of the present invention. FIGS. 7a to 7c are cross-sectional views showing part of the configuration of a display device according to one embodiment of the present invention. Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this specification, where a component (or region, layer, part, etc.) is described as being "on," "connected," or "joined" to another component, it means that it may be directly connected/joined to 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 the 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. In this specification, "directly placed" may mean that there are no additional layers, films, regions, plates, etc. between a part such as a layer, film, region, or plate and another part. For example, "directly placed" may mean placing two layers or two members without using additional members such as adhesive members between them. 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. Hereinafter, a window according to one embodiment of the present invention and a display
