  • Publication number: 20140002975
    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.

  • Publication number: 20130314881
    Abstract: A portable display device may include a display panel, a window, an attaching member and a blocking member. The display panel may have a drive circuit region and a display region. The window may be positioned facing to the display panel. The attaching member may be interposed between the display region of the display panel and the window to attach the display panel to the window. The blocking member may be arranged on a boundary line between the drive circuit region and the display region to prevent the attaching member from infiltrating into the drive circuit region. Thus, flows of the attaching member may be readily controlled using the blocking member having a simple structure to prevent the infiltration of the attaching member into the drive circuit region. As a result, the portable display device may be assembled by a simple process and a low cost.
