1. A display cover member comprising:
a light-transmissive plate including a principal surface; and
a coating film that covers at least a portion of the principal surface of the light-transmissive plate; wherein
the coating film has an uneven surface, is made of silicon oxide, contains no scattering particles, and is a homogeneous film;
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 18 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°.
