Document Type and Number:
Japanese Patent JP5724171
Kind Code:
B2
Abstract:
An optical element includes a substrate including protruding structures on the surface and a hard coat layer formed on the substrate. An irregular shape is formed by the structures. An irregular shape resembling the irregular shape of the substrate is formed on a surface of the hard coat layer and is smoother than the that of the substrate. The size of bottoms of the structures changes at random within the range of the minimum distance R m to the maximum distance R m (R m : minimum value of the shortest distance from the center of gravity of the bottom of the structure to the rim of the bottom, R M : maximum value of the longest distance from the center of gravity of the bottom of the structure to the rim of the bottom). Neighboring structures have bottoms in contact or substantially in contact with one another. R m and R m satisfy R m /R M ¤ 0.9.
