1. An article comprising an antiglare surface including six adjacent first areas, each first area having a dimension of 103 μm×118 μm and a corresponding surface shape having an arithmetic mean height Sa,
wherein an average value of the arithmetic mean heights Sa of the six first areas is 20 nm or greater and a variation coefficient CV1, based on the average value and a standard deviation of the arithmetic mean heights Sa of the six first areas, is 0.020 or greater.
