Abstract

A screen protector comprises a glass-based substrate and an adhesive. The glass-based substrate comprises a first major surface, a second major surface, a thickness, and an edge. The first major surface comprises a first planar portion and a peripheral portion extending outwardly from the first planar portion. The second major surface comprises a second planar portion opposite the first planar portion and is parallel to the first planar portion. The edge comprises an outer peripheral surface that intersects the peripheral portion of the first major surface. The adhesive comprises a first major surface, a second major surface, a thickness, and an edge. The first major surface of the adhesive is adhered to the second major surface of the glass-based substrate.
