An object of the present invention is to provide an excellent handling performance during film processing and a polarizing plate by imparting appropriate slip properties to the cyclic olefin film itself without reducing the transmittance of the cyclic olefin resin film or increasing the haze. To provide a cyclic olefin-based film that achieves excellent optical performance as a film for LCD and liquid crystal display, suppresses the occurrence of scratches and flaws during film winding, and does not cause unnecessary laminating film as waste . A cyclic olefin-based resin film having a multilayer structure having at least a base layer and a surface layer, wherein fine particles are added only to the surface layer, the average particle diameter of the fine particles is 3.0 μm or less, and Multilayer structure cyclic structure in which the relationship between the absolute value | Δn | of the refractive index difference between the cyclic olefin resin in the surface layer and the fine particles and the average particle diameter r (μm) of the fine particles satisfies | Δn | · r ≦ 0.05 (μm) Olefin resin film. A polarizing plate and a liquid crystal display device using the film. [Selection] Figure 1 |
