The protector comprises: a glass-containing substrate comprising an outer and inner primary surface; an antireflective (AR) coating on the outer primary surface; and an interlayer on the inner primary surface for releasable attachment to the optical coating on the display. The interlayer comprises an adhesive, a physical thickness from about 10 μm to 500 μm, and one or more refractive indices from ˜1.2 to 1.6. Further, an average photopic reflectance of the screen protector can be less than 2% for all incident angles from 0° to 30°. The interlayer can comprise optically clear adhesive (OCA), polymer-containing layer, and releasable adhesive layers. An anti-splinter (AS) film can be between the interlayer and the substrate. The interlayer and/or AS film may be a cyclo olefin, cellulose triacetate or polyurethane.
