Abstract
The present invention relates to an optically anisotropic sheet for transfer, comprising a substrate, and a liquid crystal cured layer laminated together, wherein the liquid crystal cured layer is to be transferred from the substrate to a receiver via an active energy ray-curable adhesive, and when the transmittance of the optically anisotropic sheet for transfer at a wavelength of 800 nm is taken as 100%, the transmittance or the optically anisotropic sheet for transfer at wavelength of 390 nm is more than 35% and less than 45%, the transmittance at a wavelength of 400 nm is more than 75% and less than 85%, and the transmittance at a wavelength of 550 nm is more than 95% and less than 100%.
