Abstract
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 μm (Ra1≥0.12 μm) and a first spacing value, Rsm1, being equal to or greater than 45 μm (Rsm1≥45 μm) 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.
