Optical Laminate And Polarizing Plate, Surface Plate, Image Display Panel, And Image Display Device Using Said Optical Laminate

Abstract: Provided is an optical laminate in which a low refractive index layer is laminated on an anti-glare layer and whereby it is possible to obtain sufficient anti-reflective properties. The optical laminate has a first surface and a second surface on the opposite side from the first surface, a low refractive index layer and an anti-glare layer are included in this order from the first side toward the second side, the low refractive index layer contains a binder resin and spherical particles with an average particle size of 20 nm or more, the first surface has an uneven shape, the "average of the exclusive area rate of the spherical particles having an average particle size of 20 nm or more" is 15.0% or more, the "average film thickness of the low refractive index layer" is 200 nm or less, and the "average of the standard deviation in the film thickness of the low refractive index layer" is 25.0 nm or less.
