Title:
OPTICAL ANISOTROPIC FILM, CIRCULARLY POLARIZING PLATE, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/044859
Kind Code:
A1
Abstract:
The present invention provides an optical anisotropic film showing excellent reverse wavelength dispersibility, a circularly polarizing plate, and a display device. The optical anisotropic film according to the present invention is formed from a composition comprising a liquid crystal compound and an infrared-absorbing dye. The optical anisotropic film satisfies the relationship of formula (A), and the absorption at a wavelength of 700-900 nm in the fast axis direction of the optical anisotropic film is higher than the absorption at a wavelength of 700-900 nm in the slow axis direction of the optical anisotropic film. Formula (A): Re(450)/Re(550) < 1
wherein Re(450) denotes the in-plane retardation of the optical anisotropic film at a wavelength of 450 nm, and Re(550) denotes the in-plane retardation of the optical anisotropic film at a wavelength of 550 nm.
