FERROELECTRIC LIQUID CRYSTAL ELEMENT

摘要

PURPOSE:To prevent the generation of an orientation defect and to permit satisfactory exhibition of the characteristics of a ferroelectric liquid crystal by providing a taper angle in a 0-90 deg. range to color filter picture elements on substrates and providing overlap parts with the adjacent picture elements in a specific range. CONSTITUTION:The respective color filter picture elements are formed to a trapezoidal shape and are preliminarily set with the concn. of coloring materials so as to have desired spectral characteristics at an equal film thickness. The picture elements are provided with the taper angles by controlling exposure to have the overlap parts with the adjacent picture elements in part of the hypotenuse thereof. More specifically, the range of the sectional taper angle of one picture element is set at 0
