Document Type and Number:
Japanese Patent JP2017097111
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an optical film excellent in irregular shape punching property and durability.SOLUTION: There is provided an optical film which contains a resin selected from the group consisting of a cycloolefin-based resin, a cellulose ester-based resin and a (meth)acrylic resin, inorganic fine particles A having a major axis and a minor axis and shape anisotropy, and inorganic fine particles B having shape isotropy, where a r/rratio of an average major axis rof the inorganic fine particles A to an average primary particle diameter rof the inorganic fine particles B is 2.5 or more and 40 or less, and tensile modulus in 45° direction to a slow axis of which a refractive index becomes largest in the plane of the optical film is more than 2.2 GPa and less than 3.5 GPa.SELECTED DRAWING: Figure 1
