Abstract
A cover glass sheet configured to cover a display element including a first textured surface having a surface roughness defined by a first arithmetic amplitude value, Ra1, and a first spacing value, Rsm1. Both values are measured on an evaluation length of 12 mm with a Gaussian filter wherein the cut-off wavelength is 0.8 mm. A first transmission haze value, Haze1, is equal to or lower than 10%. A first clarity value, Clarity1, and a second textured surface comprise a second transmission haze value, Haze2. The second transmission haze value, Haze2, of the second textured surface is equal to or lower than a maximum haze value, HazeMax (Haze2≤HazeMax), wherein HazeMax=4.99−8.13 10(Haze1)+4.67 10(Clarity1) %.
