Abstract:
Provided is a display cover member that enables realization of a display having less reflection of the background and excellent anti-sparkle properties. The display cover member has a feature that: one of principal surfaces is formed of an uneven surface; a mean width of roughness profile elements (RSm) of the uneven surface defined by JIS B 0601-2013 is not less than 1 μm and not more than 30 μm; and a ratio θ/Rku between an average inclined angle (θ) of the roughness profile of the uneven surface and a kurtosis of the roughness profile (Rku) of the uneven surface defined by JIS B 0601-2013 is not less than 0.40° and not more than 1.08°.
