The present invention provides an antireflective film including at least an antireflective layer and a base resin layer, the base resin layer including at least layers a and b respectively including a thermoplastic resin as a main component, the layer a having a flexural modulus higher than that of the layer b, and the layer a being closer to the antireflective layer than the layer b, a polarizer plate obtained by bonding the antireflective film to a polarizer, and a display including the polarizer plate. According to the present invention, an antireflective film in which an antireflective layer is stacked on a transparent resin substrate and exhibits excellent antireflective performance, tenacity, and surface hardness, a polarizer plate using the antireflective film, and a display including the polarizer plate are provided.
An antireflective film comprising at least an antireflective layer and a base resin layer, the base resin layer including at least layers a and b respectively including a thermoplastic resin as a main component, the layer a having a flexural modulus higher than that of the layer b, a difference in flexural modulus between the layers a and b is 0.2 GPa to 2.5 GPa, the layer a having a flexural modulus of 3 GPa or more,
An antireflective film comprising at least an antireflective layer and a base resin layer, the base resin layer including at least layers a and b respectively including a thermoplastic resin as a main component, the layer a having a flexural modulus higher than that of the layer b, and the layer a being closer to the antireflective layer than the layer b, wherein a combination (layer a/layer b) of the layers a and b is a vinyl aromatic polymer/alicyclic structure-containing polymer, a polyacrylate polymer/alicyclic structure-containing polymer, or a polymethacrylate polymer/alicyclic structure-containing polymer.
