PROBLEM TO BE SOLVED: To reduce interference fringes caused by reflection light, provided that an optical film has an alignment layer, phase difference layer, surface material layer sequentially arranged on one face of a base material.SOLUTION: There is provided an optical film 11 having an alignment layer 13, phase difference layer 14, and surface material layer 15 sequentially manufactured on one face of a base material 12 made of a transparent film material, where a penetration layer 12A is formed on the surface material layer 15 side of the base material 12, and the ratio of the thickness D15 of the surface material layer 15 to the thickness D12A of the penetration layer 12A (D15/D12A) is 11.5 or more and 15 or less.SELECTED DRAWING: Figure 1 |
