  • Patent number: 12225670
    Abstract: A display device includes a cover window including a curved portion, and a panel member laminated on the cover window. A method of manufacturing a display device includes mounting a cover window including a curved portion on a first jig including a curved portion, mounting a panel member on a second jig that conforms to a surface of the first jig, and laminating the cover window to the panel member by moving a first one of the first jig or the second jig to a first other one of the first jig or the second jig. An apparatus for manufacturing a display device includes a first jig including a mount surface that is partially curved to conform to a surface of a cover window, a second jig including a surface conforming to the mount surface and configured to contact a panel member, and a driving unit.
