An optical laminate is provided. When the optical laminate is applied to an OLED display device, the problem of visibility due to reflection of external incident natural light of the device can be solved, and simultaneously its display quality can also be improved.

Provided is an optical laminate produced by disposing an anti-glare layer on at least one side of a light-transmitting substrate, the anti-glare layer having a surface that has the arithmetic mean peak curvature Spc of 1.5 mm.sup.−1 or less in absolute value, the optical laminate has the adjusted transmission image clarity of 85% or less. On the anti-glare layer, further disposed is a low refractive index layer. The optical laminate including the low refractive index layer may have a luminous reflectance of 1.4 or less. The optical laminate improves the anti-glare properties.
