OPTICAL FILM AND METHOD OF MAKING SAID FILM, ANTI-GLARE POLARISER AND DISPLAY DEVICE Russian patent published in 2012 - IPC G02B5/02 

FIELD: physics.

SUBSTANCE: optical film has a base with convex structural components which are two-dimensionally and orderly formed directly on its surface, and a solid coating layer on the surface of the base, having said structural components. The surface of the solid coating layer has a continuous wavelike shape which matches the shape of structural components of the surface of the base. The maximum amplitude (A) and minimum wavelength (λ) of the continuous wavelike surface are essentially constant, and the ratio (A/λ) of the maximum amplitude (A) to the minimum wavelength (λ) is greater than 0.002 but not greater than 0.011. The film has full light transmission factor of 92% or higher, dullness of 1.5% or less, internal dullness of 0.5% or less and opacity of 0.7% or less.

EFFECT: improved anti-glare properties and contrast.
