Optical films, laminates and panel

Providing an optical film that interference fringes are not conspicuous while maintaining a high surface hardness and fluoroscopic resolution. Optical film 1 has a transparent substrate layer 12. The at least one surface of the transparent substrate layer 12, are undercoat layer 14 is laminated. On the undercoat layer 14, a transparent hard coat layer 16 are laminated. On the transparent hard coat layer 16, anti-reflection layer 18 are laminated. Antireflective layer 18 is a layer of lower refractive index and low refractive index of the transparent hard coat layer 16. The refractive index of the transparent substrate layer 12 n0, the refractive index of the undercoat layer 14 n1, the refractive index of the transparent hard coat layer 16 n2, the refractive index of the antireflection layer 18 in the case of a n3, n3
