Abstract: A device for manufacturing a 3D forming film performs molding at a uniform pressure by using a variable volume body, and thus, enables undercut portion molding, prevents thermal corrugation on the curved portion, etc., of the forming film and the distortion of the forming film, reduces a thickness deviation of the forming film and excludes an additional cutting process after molding the forming film, thereby improving the quality of the 3D-molded forming film. The device for manufacturing the 3D forming film includes: a mold for molding a forming film; a press head unit which is positioned to correspond to the mold and has a variable spaced distance from the mold; and a variable volume body which is coupled to the press head unit and has elasticity so that a volume thereof is variable due to gas introduction and discharge by the press head unit.

Abstract: Provided are a strengthened glass panel for protecting a surface of a display device and a method for manufacturing the same. Here, the strengthened glass panel includes a strengthened glass layer, a laminate layer uniformly formed on the bottom surface of the strengthened glass layer, and a separation layer configured to cover the laminate layer, wherein the laminate layer is formed by transferring a transfer film. Accordingly, the strengthened glass panel for protecting a surface of a display device can have improved characteristics of neatly attaching the laminate layer to the surface of the display device without lifting or occurrence of air bubbles and easily detaching the laminate layer when a uniform laminate layer is formed on strengthened glass by means of a transfer film.
