Optical laminate

Abstract

The object of the present invention is to provide an optical laminate capable of suppressing the disappearance of dichroic dyes from a linear polarizer and suppressing the degradation of visibility caused by unevenness. The optical laminate of the present invention sequentially comprises a first protective layer, a linear polarizer, an adhesive layer, and a retardation layer laminate. The adhesive layer has a storage elastic modulus at 25°C of 0.2 to 1.0 MPa and a thickness of 2 to 25 μm. The retardation layer laminate sequentially comprises, from the side of the adhesive layer, a first liquid crystal retardation layer, a bonding layer having a thickness of 20 to 200 nm, and a second liquid crystal retardation layer.
