Title:
ANTI-REFLECTION FILM
Document Type and Number:
WIPO Patent Application WO/2018/180504
Kind Code:
A1
Abstract:
Provided is an anti-reflection film which exhibits good optical characteristics and scratch resistance, while having improved productivity. An anti-reflection film which is obtained by sequentially laminating, on at least one surface of a transparent base film, four optical adjustment layers, namely, a first medium refractive index layer, a high refractive index layer, a low refractive index layer and a second medium refractive index layer in this order, and which is characterized in that: the first medium refractive index layer contains an inorganic material; the high refractive index material is a layer that contains an inorganic material; the low refractive index layer is a cured layer that contains a binder resin and inorganic fine particles; and the second medium refractive index layer is mainly composed of one or more materials selected from among silicon oxide, magnesium fluoride and lithium fluoride; a lubricant layer that is mainly composed of a fluorine-based lubricant having a silane coupling group is formed on the surface of the second medium refractive index layer; the first medium refractive index layer has a film thickness of 85-150 nm; the high refractive index layer has a film thickness of 20-55 nm; the low refractive index layer has a film thickness of 50-100 nm; the second medium refractive index layer has a film thickness of 10-50 nm; the first medium refractive index layer has a refractive index of 1.55-1.60; and the second medium refractive index layer has a refractive index of 1.41-1.50.
