Abstract

The present invention relates to an optical film, a manufacturing method thereof, a polarizer and a liquid crystal display device. The optical film of the present invention contains a hydrogenated norbornene-based resin and organic fine particles. The average particle diameter of the organic fine particles is 0.10 μm or more and 0.70 μm or less. The following formulas (1) to (3) are satisfied when the ten-point height is Rz (nm), the average interval of concavities and convexities is Sm (μm), and the root mean square slope is RΔq. Formula (1): 5 μm≤Sm≤10 μm Formula (2): 50nm≤Rz≤150nm Formula (3): 0.5≤RΔq≤2.0.

Description

Technical field [0001] The present invention relates to an optical film and a manufacturing method thereof, a polarizer and a liquid crystal display device. Background [0002] In recent years, the use of liquid crystal display devices, organic electroluminescent (hereinafter referred to as "organic EL") display devices, touch panels, etc. is expanding. In such a device, various resin films are used for supports, protective films, etc. Wherein, the film containing hydrogenation (hereinafter referred to as "hydrogenated") ice-reducing sheet ene film has high heat resistance and low water absorption, so it is preferable to use the excellent dimensional stability and humidity change resistance. In addition, the film containing hydrogenated falling ice flake ene resin can suppress the inherent birefringence to a lower level due to the small photoelastic modulus. Therefore, as a polarizer protective film for optically isotropic uses, it is a raw material with excellent optical proper...
