PROBLEM TO BE SOLVED: To provide a release film which is used in OCA (Optical Clear Adhesive) and prevents a problem relating to a punching failure in OCA punching.SOLUTION: A release film for an optical clear adhesive sheet comprises a base material film and a release layer formed on at least one side of the base material film. In the base material film, a maximum refractive index nTD in the film surface is 1.672-1.687, a refractive index nZ in the film thickness direction is 1.492-1.496, nZ≤0.444×nTD+0.750 is met, and intrinsic viscosity is 0.53-0.58 dl/g. |
