Description

Display device and electronic device comprising the same The present disclosure relates to a display device and an electronic device including the same. Electronic devices such as smartphones, digital cameras, laptop computers, navigation systems, and smart televisions that provide video to a user include a display device for displaying video. The display device generates video and provides video to the user through a display screen. With the recent advancement of display technology, various types of display devices are being developed. For example, diverse display devices that can be deformed into curved shapes, folded, or rolled up are being developed. These display devices are easy to carry and can enhance user convenience. FIG. 1 is a block diagram of an electronic device according to one embodiment. FIGS. 2a and FIGS. 2b are drawings for illustrating various states of an electronic device according to one embodiment. FIG. 3a is a cross-sectional view taken along A-A' of FIG. 2a, and FIG. 3b is a cross-sectional view taken along B-B' of FIG. 2b. FIG. 4 is a schematic perspective view of an electronic device according to one embodiment. FIG. 5 is a cross-sectional view of a display device according to one embodiment. FIGS. 6a and FIGS. 6b are each cross-sectional views of a display device according to one embodiment. FIG. 7 is a perspective view showing a display panel, a support member, and a release liner according to one embodiment. FIG. 8 is a plan view showing a release paper and a support member according to one embodiment. FIG. 9 is a perspective view showing a part of a release paper and a support member according to one embodiment. FIGS. 10 to 13 are schematic cross-sectional views according to a method for manufacturing a display device according to one embodiment. FIGS. 14 to 19 are plan views of a support member and a release liner according to one embodiment. Figure 20 is an image of a display device according to a comparative example. FIG. 21 is an image of a display device according to an embodiment. Hereinafter, various embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. The present invention may be embodied in various different forms and is not limited to the embodiments described herein. To clearly explain the present invention, parts unrelated to the explanation have been omitted, and the same reference numerals are used for identical or similar components throughout the specification. Furthermore, the size and thickness of each component shown in the drawings are depicted arbitrarily for convenience of explanation, and thus the present invention is not necessarily limited to what is illustrated. Thicknesses have been enlarged in the drawings to clearly represent various layers and regions. Additionally, for convenience of explanation, the thickness of some layers and regions has been exaggerated in the drawings. Furthermore, when it is said that a part, such as a layer, membrane, region, or plate, is "on" or "on" another part, this includes not only the case where it is "directly above" the other part, but also the case where there is another part in between. Conversely, when it is said that a part is "directly above" another part, it means that there is no other part in between. Also, saying that a part is "on" or "on" a reference part means that it is located above or below the reference part, and does not necessarily mean that it is located "on" or "on" in the direction opposite to gravity. Furthermore, throughout the specification, when a part is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Additionally, throughout the specification, "planar" means when the subject part is viewed from above, and "cross-sectional" means when the cross-section obtained by vertically cutting the subject part is viewed from the side.
