Laminated phase retarder, polarizing member and liquid-crystal display device
摘要:
A laminated phase retarder having: a laminate of a retardation layer A made of a thermoplastic resin exhibiting positive birefringent characteristic and a retardation layer B constituted by an oriented solidified layer of cholesteric liquid crystal exhibiting a selective reflection wavelength range not larger than 350 nm; wherein Re of the laminate is not smaller than 10 nm and RthnullRe of the laminate is not smaller than 50 nm when Re and Rth are given by Renull(nxnullny)nulld and Rthnull(nxnullnz)nulld in which nx and ny are in-plane main refractive indices, nz is a thicknesswise refractive index, and d is a layer thickness. A polarizing member having: a laminate of a laminated phase retarder defined above; and a polarizer. A liquid-crystal display device having: a liquid-crystal cell; and a laminated phase retarder or a polarizing member defined above and disposed on at least one of opposite surfaces of the liquid-crystal cell.
