Optically anisotopic film, process for producing optically anisotopic film, substrate for liquid crystal cell, and liquid crystal display device |
| abstract |
A novel optically anisotropic film useful for optical compensation of a liquid crystal display device is provided. The optically anisotropic film has a distorted twisted spiral structure, which is formed from a liquid-crystalline composition comprising a liquid-crystalline compound and at least one optically active compound the torsional force of which is changed by light. The optically anisotropic film is produced, for example by ( 1 ) heating a liquid-crystalline composition to temperature T 1 ; and ( 2 ) irradiating the liquid-crystalline composition with polarized light at temperature T 2 , provided T NI <T 1 <150° C. (XI) and T CN <T 2 <T NI (XII), wherein T NI is the temperature at which the liquid-crystalline composition phase transitions from a cholesteric phase to an isotropic phase, and T CN is the temperature at which the liquid-crystalline composition phase transitions from a crystal phase to a cholesteric phase. |
