Abstract:
1. A polarizer plate comprising at least a protective layer A, a polarizer, and a protective layer B in that order, the protective layer A including at least layers a and b respectively including a thermoplastic resin as a main component, the layer a being formed of at least one kind of resin selected from the group consisting of a vinyl aromatic polymer, a poly(meth)acrylate polymer, a polyacrylonitrile polymer, a vinyl alicyclic hydrocarbon polymer, and a hydrogenated product thereof, the layer b having a thickness of 5 to 52 μm and being formed of at least one kind of resin selected from the group consisting of an alicyclic structure-containing polymer, a cellulose polymer, a polyester polymer, a polycarbonate polymer, a polysulfone polymer, a polyethersulfone polymer, a vinyl chloride polymer, and a poly(meth)acrylate polymer, the flexural modulus of the layer b being 2.1 to 3GPa, and the flexural modulus of layer a being higher than the flexural modulus of layer b.
