Latest Patents
Kenji Mishima holds a patent for a retardation film, an elongated circularly polarizing plate, and an organic EL display produced using this retardation film. The retardation film features a slow axis with an angle ranging from 10 to 80 degrees relative to its longitudinal direction. It contains cellulose acylate with a degree of acyl substitution between 2.0 and 2.7, along with a regulating agent. The film exhibits an in-plane retardation, measured at a wavelength of 550 nm, with values ranging from 115 to 260 nm. Additionally, the retardation film has a ΔRo of 3 to 30 nm, where ΔRo is defined as Ro550 minus Ro450, with Ro450 being the in-plane retardation measured at a wavelength of 450 nm. The film, when devoid of the regulating agent, maintains an in-plane retardation of Rc550 at 550 nm, with ΔRc (Rc550 minus Rc450) being equal to or greater than 0.
