Implementations for composite display cover are described and provide improved protection and durability to device displays as compared with conventional display protection technologies. The described composite display cover, for instance, utilizes an ultra-thin glass layer with a polymer film applied directly to the glass layer and a hard coat applied to the polymer film. The polymer film, for instance, is applied to the glass layer without an adhesive. Further, the composite display cover can be attached to a display, such as via an adhesive layer that adheres the glass layer to a surface of the display.
