Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the priority of Korean Patent Application No. 10-2023-0115321 filed on August 31, 2023 and No. 10-2024-0083837 filed on June 26, 2024, in the Korean Intellectual Property Office, the disclosure of which are incorporated herein by reference. BACKGROUND Field The present disclosure relates to a display device. Description of the Related Art As it enters an information era, a display field which visually expresses electrical information signals has been rapidly developed, and in response to this, various display devices having excellent performances such as thin-thickness, light weight, and low power consumption have been developed. Examples of such a display device include a liquid crystal display device (LCD), an organic light emitting display device (OLED), and the like. An applicable range of the display device is diversified to personal digital assistants as well as monitors of computers and televisions, and a display device with a large display area and a reduced volume and weight is being studied. Recently, a display device which is manufactured by forming a display unit, a wiring line, and the like on a flexible substrate such as plastic which is a flexible material so as to be stretchable in a specific direction and changeable in various forms is getting attention as a next generation display device. SUMMARY An object to be achieved by the present disclosure is to provide a display device which minimizes a bezel area. Another object to be achieved by the present disclosure is to provide a display device in which an outer peripheral area can be modified to have a curved shape.
