Abstract
(EN)
An optical laminate which is provided with a base layer and a first surface layer, and wherein: the base layer contains an amorphous polymer containing an alicyclic structure; and the first surface layer contains a crystalline polymer containing an alicyclic structure. A polarizing plate which comprises the above-described optical laminate and a polarizer; and a liquid crystal display device which is provided with this polarizing plate. It is preferable that: the optical laminate has a specific retardation; the first surface layer has a specific thickness; and the crystalline polymer containing an alicyclic structure is a hydrogenated product of a ring-opening polymer of dicyclopentadiene.
