PURPOSE:To provide a liquid crystal display device having a wide visual field angle to substantially prevent degradation in contrast and increase of a driving voltage without drastically increasing the number of stages and equipment. CONSTITUTION:This liquid crystal display device is generated with high pretilt angle parts 51, 52 and low pretilt angle parts 50, 53 by irradiation of oriented films 50 to 53 with UV rays, printing of many kinds of the oriented films, rubbing treatment to change the rubbing strength and adequate adjustment of chiral agents so that the orientation of the liquid crystal molecules in one pixel consists of plural domains. The liquid crystal display device of the wide visual field angle is realized by the liquid crystal display device generated with the high and low pretilt angles by the irradiation of the oriented films 50 to 53 with the UV rays and printing of many kinds of the oriented films. Further, the degradation in contrast is prevented by a phase difference plate 20, a high-dielectric constant anisotropic liquid crystal, conversion of a common voltage to AC and introduction of active elements 42 and the driving voltage is lowered. The high-fineness liquid crystal display device is thus provided. |
