1. An optical laminate comprising: a polymer substrate containing a polymer resin and rubber particles having a cross-sectional diameter of 10 to 500 nm dispersed in the polymer resin; and
an antiglare layer containing a binder resin and organic fine particles, nano-inorganic particles and chain-shaped silica dispersed in the binder resin,
wherein the rubber particles having a cross-sectional diameter of 10 to 500 nm exist within 50% of a thickness of the antiglare layer from an interface between the polymer substrate and the antiglare layer.
