摘要: The present invention can provide a polymer film having an Ra (arithmetic average roughness) of 0.5 μm to 2.5 μm, an Ry (maximum height) of 3 μm to 11 μm, an Rz (ten-point average height) of 3 μm to 8 μm, and a light transmittance of 85% or higher. A preferable embodiment of the present invention can provide, at the same time, an optical diffusion function, an improved luminance, a transmittance and the like which are of a sufficient level not realized conventionally. In a still preferable embodiment, Sm (average concave-concave/convex-convex interval) of 90 μm to 160 μm and the average inter-local peak interval (S) is 5 μm to 15 μm.
