Abstract:
The present invention provides an anti-dazzling laminate which has anti-dazzling properties and can realize excellent glare preventive properties and black color reproducibility, such as gradation rendering of black color at low brightness. The optical laminate comprises a light transparent base material and an anti-dazzling layer provided on the light transparent base material. The outermost surface of the anti-dazzling layer has a concavoconvex surface, and the average spacing S determined by calculation based on data obtained by measuring a roughness curve of a concavoconvex shape of the anti-dazzling layer is not less than 0.04 mm and not more than 0.30 mm.
