FERROELECTRIC LIQUID CRYSTAL DISPLAY HAVING A SPREAD OF ANGLES FOR GRAYSCALE AND METHOD OF MANUFACTURE |
摘要 |
A liquid crystal device incorporating ferroelectric liquid crystal medium having smectic layers between two supporting plates provided with electrodes, the smectic layers exhibiting a spread of angles with respect to at least one of the supporting plates, whereby a gradual transmission/voltage characteristic is achieved. The spread of angles can be obtained by any of several techniques, such as subjecting the device to a low frequency electric field, or a local thermal, mechanical, chemical or magnetic treatment.
