Abstract
The present invention relates to an antiglare film laminate including a polymer substrate, and an antiglare layer containing a binder resin and organic fine particles or inorganic fine particles dispersed on the binder resin, wherein the number of pressed portions formed on an outer surface of the antiglare layer is 0.001 pieces/m2 or less, and the pressed portion has a diameter of 200 μm to 600 μm and a thickness of 80% or less of an average thickness of the antiglare layer, a polarizing plate including the antiglare film laminate, and a display device including the polarizing plate.
Claims8
An antiglare film laminate, comprising:
- a polymer substrate;
- and
- an antiglare layer comprising a binder resin, a silicon-based additive, a fluorine-based additive, and organic fine particles and inorganic fine particles dispersed on the binder resin,
- wherein the number of pressed portions formed on an outer surface of the antiglare layer is 0.001 pieces/m2,
- each pressed portion has a diameter of 200 μm to 600 μm and a thickness of 80% or less of an average thickness of the antiglare layer,
- the antiglare layer has a thickness of 1 to 10 μm,
- the antiglare layer comprises 0.3 parts by weight or more of the fluorine-based additive and 0.25 parts by weight or more of the silicon-based additive based on 100 parts by weight of the binder resin,
- the antiglare layer comprises 1 to 10 parts by weight of the organic fine particles and 0.1 to 5 parts by weight of the inorganic fine particles based on 100 parts by weight of the binder resin,
- a weight ratio of fluorine (F)/carbon (C) element on a surface of the antiglare layer excluding the pressed portion(s) is 10% or more,
- a weight ratio of silicon (Si)/carbon (C) element on the surface of the antiglare layer excluding the pressed portion(s) is 5 to 15%, and
- on the surface of the antiglare layer excluding the pressed portion(s), a weight ratio of a total of the fluorine (F) and silicon (Si) elements/carbon (C) element is 20 to 35%,
- wherein:
- the polymer substrate has a thickness of 10 to 150 μm,
- wherein:
- an arithmetic average roughness (Ra) measured on the surface of the antiglare layer is 100 nm or less,
- wherein:
- a weight ratio of fluorine (F)/carbon (C) element in the pressed portion is 3.0% or less.
