发明名称 LIQUID CRYSTAL DISPLAY ELEMENT
摘要 PURPOSE:To provide the liquid crystal display element which can be easily produced and can make high-grade display with suppressed uneven display at a high response speed and wide visual field angle. CONSTITUTION:This liquid crystal display element is constituted by superposing a liquid crystal cell 200 for phase difference compensation for compensating the refractive index anisotropy of a liquid crystal cell 100 for driving having a nematic liquid crystal layer which is homogeneously arranged and has positive dielectric anisotropy on the liquid crystal cell for driving and holding the liquid crystal display cell 100 for driving and the liquid crystal cell 200 for phase difference compensation with two sheets of polarizing plates 301, 303. The liquid crystal cell 200 for phase difference compensation is formed to a twisted structure having the spiral axis of the liquid crystal layer in the direction normal to the plane of the cell and about 180 deg. twist angle, by which the larger margin for a cell gap is obtd.
