摘要： PURPOSE: To obtain a liquid crystal panel having an excellent contrast and visual angle characteristics by using perpendicularly oriented films and composing these oriented films of fine printing patterns of orienting materials. CONSTITUTION: This liquid crystal panel is provided with a pair of transparent substrates 12, 14 sealed with liquid crystals 10 and is provided with transparent pixel electrodes 20 and the perpendicularly oriented film 22 on the inside surface of the one substrate 12 and color filters 24, transparent common electrodes 26 and the perpendicularly oriented film 28 on the inside surface of another substrate 14. The micro-region corresponding to one pixel is divided to domains A, B varying in the visual angle characteristics by 180 deg.. The films 22, 28 are formed as two layers of orienting material layers 22a-22b, 28a-28b and the layers 22a, 28a on the lower layer side are printed solid. The layers 22b, 28b on the upper layer side are printed in the fine patterns corresponding to the domains A, B. The layers 22a, 28a and 22b, 28b are so subjected to orientation treatments that the pretilts of the liquid crystal molecules in contact therewith change. As a result, the damage of the ground substrate and the roughening of the traces of the rubbing do not arise and, therefore, the effect of the division in the orientation is sufficiently manifested.

The oriented films 37, 38 are subjected to orientation treatments in such a manner that twist angles varying from each other are imparted on the liquid crystal molecules of the liquid crystal layer 31 in the two regions. The voltage impressing means impresses the voltages of the magnitude varying from each other on the electrodes 32, 33 for impressing the electric fields respectively on the two regions. The magnitude of the voltages is so selected that the contrast ratio in the two regions is made more uniform than when the equal voltage is impressed on the electrodes.
