Abstract
This invention provides an anti-reflection film for use in various displays which prevents the reflection of light on the surface and enables necessary visual information to be clearly discerned. The anti-reflection film has a hard coat layer 4, an intermediate refractive index layer 3, a high refractive index layer 2 and a low refractive index layer 1 formed in this sequence on a transparent base film 5, such that the refractive indices of the adjacent layers satisfy the relationship 2.20>refractive index of the high refractive index layer>refractive index of the intermediate refractive index layer>refractive index of the low refractive index layer >1.40.
