8 . The method of claim 7 , wherein the first curing device and the second curing device are spaced apart from each other in a first direction.
9 . The method of claim 7 , wherein a wavelength band of light irradiated by the first curing device and the second curing device is equal to or greater than 365 nm and equal to or less than 405 nm, wherein an irradiation amount of light irradiated by the first curing device and the second curing device is determined so that a curing rate of the first material and the second material at a deep portion and a surface is equal to or greater than 80%.

Description

CROSS-REFERENCE TO RELATED APPLICATION The present application claims priority to and the benefit of Korean Patent Application No. 10-2022-0096268, filed on Aug. 2, 2022, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference. BACKGROUND 1. Field Aspects of one or more embodiments relate to an apparatus and method for manufacturing a display apparatus. 2. Description of the Related Art Recently, electronic devices have been widely used. Electronic devices have been variously used as mobile electronic devices and fixed electronic devices. Such electronic devices include display apparatuses that may provide a user with visual information such as images or videos to support various functions. Recently, as other components for driving a display apparatus have been miniaturized, the proportion of the display apparatus in an electronic device has gradually increased, and a structure that is bendable from a flat state to have a certain angle or is foldable about an axis has been developed. In general, a display apparatus includes a display panel, and the display panel includes a display area where an image is displayed and a peripheral area that is a non-display area adjacent to the display area. In the display panel, visibility at various angles may be improved or the area of the non-display area may be reduced by bending at least a part of the peripheral area. The above information disclosed in this Background section is only for enhancement of understanding of the background and therefore the information discussed in this Background section does not necessarily constitute prior art. SUMMARY Aspects of one or more embodiments include an apparatus and method for manufacturing a display apparatus in which a time of a manufacturing process may be relatively reduced by respectively applying materials to an adjacent area and a bending area of a display panel and then simultaneously (or concurrently) curing the applied materials. However, the above-described characteristics are only examples according to some embodiments, and do not limit the scope of embodiments according to the present disclosure. Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments. According to one or more embodiments, an apparatus for manufacturing a display apparatus includes a display panel including a display area, an adjacent area surrounding the display area, and a bending area extending from a side of the adjacent area, the display panel including a first material located in the adjacent area and a second material located in the bending area, a stage on which the display panel is located, and a curing device configured to simultaneously (or concurrently) cure the first material and the second material. According to some embodiments, the display panel may further include a dam located in at least a part of the adjacent area and at least a part of the bending area. According to some embodiments, the dam may include a same material as the second material. According to some embodiments, the first material may cover a top surface of the display panel so that the top surface of the display panel in the adjacent area is not exposed. According to some embodiments, the first material in the adjacent area may be cured to form an organic material layer. According to some embodiments, the second material in the bending area may be cured to form a bending protective layer. According to some embodiments, a wavelength band of light irradiated by the curing device may be equal to or greater than 365 nm and equal to or less than 405 nm. According to some embodiments, an irradiation amount of light irradiated by the curing device may be determined so that a curing rate of the first material in the adjacent area and the second material in the bending area at a deep portion and a surface is equal to or greater than 80%. According to some embodiments, the curing device may include a first curing device configured to cure the first material in the adjacent area and a second curing device configured to cure the second material in the bending area, wherein the first curing device and the second curing device are spaced apart from each other in a first direction. According to some embodiments, a wavelength band of light irradiated by each of the first curing device and the second curing device may be equal to or greater than 365 nm and equal to or less than 405 nm.
