Patent ID: 7931953

Claim:
An optical laminate comprising: a light transparent base material; and an anti-dazzling layer provided on the light transparent base material; wherein an outermost surface of the anti-dazzling layer has a concavoconvex shape, and the concavoconvex shape of the anti-dazzling layer has an average spacing S of not less than 0.04 mm and not more than 0.30 mm; wherein the average spacing S is determined by measuring a roughness curve for the concavoconvex shape of the anti-dazzling layer, drawing an average line in the roughness curve, sampling a reference length from the average line, measuring a total number m of convex peaks present on a part above and below the average line within the reference length, introducing the value Si of length between the top of the mth highest convex peak and the top of the (m−1)th highest convex peak and the number n of Si into the following mathematical formula (I): S ′ = 1 n ⁢ ∑ i = 1 n ⁢ S i ( I ) to determine S′, repeating the procedure of determining S′ value within a next identical reference length N times, and introducing S′j, which represents S′ value determined in mathematical formula (I) and N, which represents the number of S′j, into the following mathematical formula (II): S = 1 N ⁢ ∑ j = 1 N ⁢ S j ′ ( II ) to obtain the average spacing S.
