Abstract

PURPOSE: To regulate the arrangement of the liquid crystal molecule, and to improve displaying quality by preventing occurance of the induction domain, and to highten the rising characteristics, and to make a dynamic drive possible, and to heighten the contrast, and to improve view for easier recognition by fitting it with a slanted evaporation bonded film.
