Title: Liquid crystal display element
Inventor: OKUMURA OSAMU
IPC: G02F1/133
Filed: 1987-08-20
Abstract: PURPOSE:To increase response speed and to enhance display contrast of a liquid crystal display element by setting retardation defined by a product of index of double refraction of an optically anisotropic body multiplied by a layer thickness to a smaller value than the retardation of the liquid crystal display element. CONSTITUTION:A set value of retardation of an optically anisotropic body defined by a product of its index of double refraction (DELTAnN) multiplied by its thickness of layer (dN) is regulated to a smaller value than the retardation (DELTAnS.dS) of a liquid crystal element. When a difference between a retardation of a liquid cell and that of an optically anisotropic body for light having 550nm wavelength (DELTAnS.dS-DELTAnN.dN) exceeds 0.3mum, the practicality is impaired remarkably because of deterioration of transmittance at ON stage. Therefore, the difference of retardation is preferred to be <=0.3mum. When it is <0.04mum, no difference of response speed and contrast to those of conventional elements is not recognized. Accordingly, the difference of retardation is preferred to be 0.04-0.3mum. By this constitution, a liquid crystal display element having high response speed and high contrast is obtd. inexpensively.
