Title:
LIQUID CRYSTAL PANEL AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/239794
Kind Code:
A1
Abstract:
A liquid crystal panel (101) is provided with a liquid crystal cell (20), a first polarizer (30), a second polarizer (40), and an optically anisotropic element (50). The liquid crystal cell is provided with a liquid crystal layer including liquid crystal molecules in a homogeneous alignment in the absence of an electric field, and a color filter (22) disposed on a first principal surface of the liquid crystal layer. The slow-axis direction (53) of the optically anisotropic element (50) and the absorption axis direction (45) of the second polarizer are parallel. The thickness-direction retardation of the optically anisotropic element and the thickness-direction retardation of the color filter of the liquid crystal cell satisfy a predetermined relationship for each of a wavelength of 550 nm and a wavelength of 650 nm.
