Abstract: A display device and a method of manufacturing the same are provided. The display device comprises a substrate comprising a display area in which emission areas are arranged, a main non-display area around the display area, a hole area surrounded by the display area, and an additional non-display area between the hole area and the display area; a circuit layer; a light emitting element layer; a sealing layer; a through portion in the hole area and penetrating at least the substrate; and sealing auxiliary structures in the additional non-display area and sequentially surrounding the hole area. Each of the sealing auxiliary structures comprises a first undercut portion in which a first cover layer protrudes from a first main layer; and a second undercut portion in which a second cover layer protrudes from a second main layer.

Abstract: The present invention relates to a method for preparing an alkali metal ion conductive chalcogenide-based solid electrolyte, a solid electrolyte prepared thereby, and an all-solid-state battery comprising the same.

Abstract: A method and system for providing a ticket to a user using a portable terminal and using the provided ticket are provided. The method for providing a ticket involves a server capable of issuing the ticket and a ticket issuer issuing the ticket requested to be issued by the portable terminal using wired or wireless communication in the form of e-ticket and storing information related to the ticket issued in the terminal. The method for using a ticket involves a ticket authentication/entry processor requesting the ticket server that issues the ticket an inquiry for the ticket related information upon receipt of the ticket related information using wired or wireless communication and determining whether the user of the terminal is allowed an entry depending on the inquiry result. Accordingly, the loss of tickets for accessing events or facilities can be prevented, and resources can be saved since digital transactions eliminate a need to use tickets in a printed form.

Abstract: A system and method for providing information services using a bar code at a wireless terminal, which is capable of receiving a variety of information services including user authentication through a network by receiving a bar code from a wireless terminal over the Internet and reading the transmitted bar code from a bar code system of a member store. The bar code system is constructed such that various services may be offered through a bar code system associated with a bar code issue server using a bar code transmitted to the wireless terminal through the Internet. Accordingly, the information service system and method are provided for various on line business services while not substantially modifying conventional bar code systems. Also, a bar code service can be offered through the wireless terminal, thereby allowing for excellent mobility compared with the conventional bar code system.
