ANTI-GLARE SUBSTRATE FOR A DISPLAY ARTICLE INCLUDING A TEXTURED REGION WITH PRIMARY SURFACE FEATURES AND SECONDARY SURFACE FEATURES IMPARTING A SURFACE ROUGHNESS THAT INCREASES SURFACE SCATTERING
A substrate for a display article is described herein that includes (a) a primary surface; and (b) a textured region on at least a portion of the primary surface; the textured region comprising: (i) primary surface features, each comprising a perimeter parallel to a base-plane extending through the substrate disposed below the textured region, wherein the perimeter of each of the primary surface features comprises a longest dimension of at least 5 µm; and (ii) one or more sections each comprising secondary surface features having a surface roughness (Ra) within a range of 5 nm to 100 nm. In some instances, an arrangement of the surface features reflect a random distribution. A method of forming the same is disclosed.
