Abstract
The liquid crystal display panel which has improved viewing angle characteristics, is free from deterioration of a liquid crystal, enables the alignment division to be easily and ensurely carried out and has a simple structure. The liquid crystal display panel is constructed so that substrates sandwiching a liquid crystal therebetween each have an alignment film at their inner walls, at least one of the alignment films comprises a layer of a particular polyimide film material capable of inducing a change in surface energy upon the action of light or heat energy, the alignment film comprises an assembly of two adjacent minute domains and has been continuously rubbed in one direction along the minute domains and the two minute domains are different from each other in pretilt angle (defined as an angle at which liquid crystalline molecules rise from the surface of the substrate).
