Embodiments of the present disclosure provide for methods of making substrates having an (AR) antireflective layer, substrates having an antireflective layer, devices including a substrate having an antireflective layer, and the like. The AR layer can have a total specular reflection of less than 10% at a wavelength of about 400-800 nm, and a height of about 500-1000 nm.

A waveguide head-up display (HUD) includes a waveguide that includes a lower surface and an upper surface and is configured to receive an input and project, based on the input, at least one image from the upper surface and into an eyebox, and a prism arranged at least one of on and above the waveguide. The prism includes a lower surface facing the waveguide and configured to receive the at least one image and an upper surface opposite the lower surface configured to project the at least one image received via the lower surface of the prism. The upper surface of the prism is angled relative to the upper surface of the waveguide such that a first normal of the upper surface of the prism is different from a second normal of the upper surface of the waveguide.

An anti-glare film is disclosed. The anti-glare film comprises a transparent substrate and an anti-glare layer comprising an acrylic binder resin, a polyether-modified siloxane and a plurality of silica nanoparticles, wherein the silica nanoparticles are flocculated into a micro-floccule with an average secondary particle diameter of 1,500 nm to 3,100 nm. The present anti-glare film can provide a reliable anti-glare property with low haze and fine surface.
