Abstract: A display module includes a display panel and a window. The window includes a base substrate and a plurality of functional layers. A central portion of the base substrate is flat, and an edge portion of the base substrate has a rounded shape. An upper portion of the edge portion of the window has the rounded shape and thus protrudes from a lower portion of the edge portion toward the outside. A first functional layer of the plurality of functional layers includes an acrylic-based material and/or an epoxy-based material, and a second functional layer of the plurality of functional layers includes a fluorine-based material.

Abstract: A vacuum thermoforming apparatus including: a molding machine on which a window base material is mounted; and a pressure supply machine coupled to the molding machine and configured to supply a pneumatic pressure toward the molding machine. The molding machine includes a mounting part having a curved surface-shaped mounting surface, and a coupling part having a structure for coupling with the pressure supply machine and a curved portion along the shape of the mounting part. The pressure supply machine includes: a cover part facing the mounting surface; and a side wall extending from the cover part to define an inner space in the pressure supply machine, the side wall having a curved upper surface so as to engage with the coupling part.
