1. A transparent film, comprising a cyclic olefin resin having a refractive index of n1 and a glass transition point (Tg) of 170° C. or more, and
at least one styrene based elastomer having a refractive index of n2 so that Δn=|n2−n1| is 0.012 or less, wherein an internal haze value of a test piece having a thickness of 100 μm is 1.0% or less as measured in a polyethylene glycol liquid in accordance with JIS K7136, wherein the transparent film comprises said at least one styrene based elastomer having a melt index (MI) smaller than that of the cyclic olefin resin at 270° C. and at a load of 2.16 kg. |
