    Abstract: The retardation film has a slow axis with an angle of 10 to 80° with respect to a longitudinal direction thereof and contains cellulose acylate having a degree of acyl substitution of 2.0 to 2.7 and a regulating agent. The retardation film has an in-plane retardation, measured at a wavelength of 550 nm, Ro550, of 115 to 260 nm. The retardation film has a ΔRo is 3 to 30 nm, where ΔRo is Ro550−Ro450, where Ro450 is the in-plane retardation of the film measured at a wavelength of 450 nm. The retardation film without the regulating agent has an in plane retardation, measured at a wavelength of 550 nm, Rc550, and ΔRc(Rc550−Rc450) equal to or greater than 0, where Rc450 is the in-plane retardation measured a wavelength of 450 nm.

    Abstract: The present invention provides a formed article, or more specifically a transparent substrate, which effectively utilizes a natural stuff and which has a low linear expansion coefficient, a high light transmittance and an appropriate level of moisture permeability. The transparent substrate includes at least an oxidized polysaccharide and has a linear expansion coefficient of 50 ppm/° C. or less at 30-150° C. and a light transmittance of 70% or more at 660 nm. Its manufacturing method includes an oxidation process in which cellulose reacts with TEMPO or its derivatives as a catalyst to be oxidized in water under the presence of a co-oxidant, along with a fiberizing process in which the oxidized cellulose is fiberized in water to form a cellulose fiber, and a substrate-forming process in which a transparent substrate is formed from a cellulose dispersion liquid containing the cellulose fiber.
