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.
