Title:
LIQUID CRYSTAL COMPOSITION, OPTICALLY ANISOTROPIC FILM, OPTICAL FILM, POLARIZING PLATE AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/022429
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a liquid crystal composition used to form an optically anisotropic film having excellent wet heat durability; an optically anisotropic film; an optical film; a polarizing plate; and an image display device. This liquid crystal composition contains: a liquid crystal compound having reverse wavelength dispersion properties; and a compound represented by formula (I), which has normal wavelength dispersion properties. Formula (I): R1-C(=O)-Cy1-Cy2-C(=O)-R2 In formula (I), Cy1 and Cy2 each denote an optionally substituted 1,4-cyclohexylene group, and R1 and R2 each independently denote a hydrogen atom or a substituent group.
