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) %.

Cover glass sheet

A display device with a display element having a display surface and a cover glass sheet, having a first textured surface, such that the first textured surface is facing the display element. The first textured surface has a surface roughness defined by a first arithmetic amplitude value, Ra1, being equal to or greater than 0.12 &#x3bc;m (Ra1&#x2265;0.12 &#x3bc;m) and a first spacing value, Rsm1, being equal to or greater than 45 &#x3bc;m (Rsm1&#x2265;45 &#x3bc;m) both measured on an evaluation length of 12 mm and with a Gaussian filter of which the cut-off wavelength is 0.8 mm. The first textured surface is in direct contact with the display surface over at least a portion of a contact area of the first textured surface.
