Document Type and Number:
Japanese Patent JP2017040937
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an optical laminate capable of sufficiently suppressing occurrence of interference fringes and curls, reducing film thickness of an optical functional layer, and preventing increase in manufacturing costs.SOLUTION: An optical laminate includes an optical functional layer on one surface of light-transmissive base material. The optical functional layer has an uneven shape on a surface. In the uneven shape, when an average inclination angle of an uneven part is θa, and skewness of the uneven part is Sk, an absolute value of the Sk and the θa satisfy the following formula: 0.01°≤θa≤0.10°, |Sk|≤0.5.SELECTED DRAWING: None
