Liquid-crystal display element

Abstract

Abstract PURPOSE: To prevent the occurrence of uneven colors and improve display quality by using uniaxially stretched films in which the stretching axis direction, the rubbing direction of orientation control films and the polarizing axis direction of polarizing plates are made roughly parallel or perpendicular. CONSTITUTION: Two sheets of uniaxially stretched plastic films 1 in which the stretching axis direction, the rubbing direction of orientation control films 3 and the polarizing axis direction of polarizing plates 7 are made roughly parallel or perpendicular are used as substrates. Electrodes 2 and the orientation control films 3 are deposited and formed on the inside surfaces of these films 1, and a sealing material 4 is coated on the circumferential edge part thereof, whereby a liquid crystal cell 5 is constituted. A liquid crystal 6 of which the liquid crystal molecules have roughly 90° twisted structure on account of the control films 3 is sealed in this cell 5, and the polarizing plates 7 are disposed on the outside surfaces of the cell 5. Thereby, the double refractive effect of the films 1 and the liquid crystal 6 may be decreased and the TN liquid crystal display element of good display quality is obtained.
