  "abstract": "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.",
  "claims": [
    "1. A method of manufacturing a display device, the method comprising: mounting a cover window comprising a flat portion having curved both ends on a first jig comprising 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 at least one of a first one of the first jig or the second jig to a first other one of the first jig or the second jig to press the cover window and the panel member against each other.",
    "2. The method of claim 1, wherein at least a portion of the panel member contacts a surface of the second jig.",
    "3. A method of manufacturing a display device, the method comprising: mounting a cover window comprising a flat portion having curved both ends on a first jig comprising 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 at least one of a first one of the first jig or the second jig to a first other one of the first jig or the second jig, wherein the panel member is bent along an outer surface of the second jig during the mounting of the panel member on the second jig.",
    "4. The method of claim 1, wherein the panel member is smaller in at least one of a length or a width than the cover window.",
    "5. A method of manufacturing a display device, the method comprising: mounting a cover window comprising a flat portion having curved both ends on a first jig comprising 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 at least one of a first one of the first jig or the second jig to a first other one of the first jig or the second jig, wherein the panel member is flat during the mounting of the panel member on the second jig, and the laminating of the cover window to the panel member comprises partially curving the panel member by the moving of the first one of the first jig or the second jig.",
    "6. The method of claim 1, wherein the first one of the first jig or the second jig is above the first other one of the first jig or the second jig, or the first other one of the first jig or the second jig is above the first one of the first jig or the second jig.",
    "7. The method of claim 1, wherein the first one of the first jig or the second jig is formed by protruding toward or recessing away from the first other one of the first jig or the second jig.",
    "8. The method of claim 7, wherein the first other one of the first jig or the second jig is formed by recessing away from or protruding toward the first one of the first jig or the second jig.",
    "9. The method of claim 1, wherein the mounting of the panel member comprises fixing the panel member to the second jig.",
    "10. The method of claim 1, wherein the panel member is flexible.",
    "11. The method of claim 1, wherein the panel member is attached to a recessed outer surface of the cover window or a protruding outer surface of the cover window.",
    "12. The method of claim 1, wherein the panel member comprises at least one of a display panel or a touch screen panel (TSP).",
    "13. The method of claim 1, wherein the cover window and the panel member are pressed against each other with a load of 0.3 MPa to 0.5 MPa.",
    "14. The method of claim 1, wherein the cover window and the panel member are pressed against each other with an adhesive layer therebetween."

  "description_excerpt": "1. Field\n\nAspects of embodiments of the present invention relate to a method and apparatus for manufacturing the display device.\n\n2. Description of the Related Art\n\nElectronic devices based on portability are widely used. Portable electronic devices that have recently been widely used include small electronic devices such as mobile phones as well as tablet personal computers (PCs). In order to support various functions, portable electronic devices include a display device for providing visual information such as an image to a user. Recently, as sizes of components for driving display devices have decreased, the importance of display devices in electronic devices has increased. Accordingly, display devices (such as flexible display devices) that bend at a set angle (for example, a predetermined angle) have been developed.\n\nIn general, flexible display devices that may bend at a set angle may be manufactured using a flexible process, such as being flexibly manufactured. Since a flexible display device may be formed of a flexible material, the flexible display device may have any of various shapes. A flexible display device may be manufactured by forming a light-emitting unit on a substrate to form a display unit, and sealing the display unit by using an encapsulation unit, which may increase a lifetime of the display unit. The substrate may be formed of a flexible material, and the encapsulation unit may be formed, for example, as a substrate or a thin film. As designs of electronic devices have recently been diversified, demands for flexible display devices have increased.",
