Patent ID: 8163393

Claim:
An optical laminate comprising: a light transparent base material; and an anti-dazzling layer provided on the light transparent base material, said anti-dazzling layer comprising a substrate concavoconvex layer and a surface modifying layer formed thereon, wherein an outermost surface of the anti-dazzling layer has a concavoconvex shape; wherein the optical laminate satisfies the following requirements: Ha is more than 0% and less than 8%, Hi is more than 0% and not more than 6%, Hi/Ha is not less than 0.013 and less than 0.8, Sm is not less than 100 μm and not more than 450 μm, θa is not less than 0.3 degrees and not more than 0.8 degrees, Rz is not less than 0.4 μm and not more than 1.6 μm, and Ra is not less than 0.1 μm and not more than 0.25 μm, wherein Ha represents a whole haze value of the optical laminate, Hi represents an internal haze value of the optical laminate, Sm represents an average spacing of profile irregularities of the anti-dazzling layer, θa represents an average inclination angle of the concavoconvex portion of the anti-dazzling layer, Rz represents a 10-point average roughness and Ra represents an arithmetical roughness; and wherein measurements of Sm, θa, Rz and Ra are carried out under measuring conditions for a surface roughness measuring device comprising a reference length, which is a cut-off value of roughness curve λc, of 0.8 mm, an evaluation length, which is the reference length cut-off value λc×5, of 4.0 mm, and a tracer feed speed of 0.1 mm/sec.
