Abstract: Provided are: a polymer film of which film strength is difficult to be degraded and which has a lower reflectance, even when an additive is used, and an optical member, a polarizing member, and a display device employing the same. A low refractive index layer (the polymer film 13) includes a binder 132 including a product obtained by photopolymerizing a mixture of a side-chain-reactive photopolymerizable fluoropolymer and a siloxane compound. Further, the low refractive index layer 13 includes hollow silica particles 131 distributed in the binder 132. Further, the low refractive index layer 13 includes a product obtained by photopolymerizing a one-end reactive-type photopolymerizable fluoropolymer, and a modified silicone, which are mainly distributed in a surface side.
