OPTICAL LAMINATE, PRODUCTION METHOD OF OPTICAL LAMINATE, OPTICAL MEMBER, OPTICAL DEVICE, PRODUCTION METHOD OF OPTICAL MEMBER, AND PRODUCTION METHOD OF OPTICAL DEVICE
Document Type and Number:
Japanese Patent JP2022155373
Kind Code:
A
Abstract:
To provide an optical laminate having high strength against tearing a void layer, production method of an optical laminate, an optical member, an optical device, a production method of an optical member, and a production method of an optical device.SOLUTION: An optical laminate 10a or 10b of the invention includes a void layer 12 and a hard layer 13 formed on the void layer 12. The void layer 12 has a void ratio of 30 vol.% or more. The hard layer 13 contains at least one selected from the group consisting of a metal, a metal oxide, silicon, a silicon oxide, and an organic-inorganic hybrid material and has a hardness higher than that of the void layer 12, the hardness measured by pushing an indenter into the hard layer 13 by 20 nm using a nanoindenter.SELECTED DRAWING: Figure 1
