The present invention provides an optical film which is capable of impeding the occurrence of a failure of display quality at wide view angles, impeding the occurrence of the degradation of the front contrast, achieving a high transmission image definition, and impeding the occurrence of scintillation, and a liquid crystal display device comprising the same. On a substrate film 71, an anti-glare layer 72 in which translucent fine particles 722 are dispersed and mixed in a translucent resin 721 is laminated. The average particle size of the translucent fine particles 722 is set at 0.5 μm or more and less than 5 μm, and the content of the translucent fine particles 722 is set at 35 parts by weight or more and 60 parts by weight or less in relation to 100 parts by weight of the translucent resin. The layer thickness of the anti-glare layer 72 is set at one or more and three or less times the average particle size of the translucent fine particles 722. It is preferable to make the refractive index of the translucent fine particles 722 larger than the refractive index of the translucent resin 721, and the difference between the refractive index of the translucent fine particles 722 and the refractive index of the translucent resin 721 is preferably 0.04 or more and 0.1 or less. |
