Abstract
A liquid crystal display panel comprises first and second substrates and a liquid crystal inserted therebetween. The first substrate has active elements, picture electrodes and a first alignment film, and the second substrate has a common electrode and a second alignment film. The first and second alignment films are treated such that the liquid crystal molecules adjacent to the alignment films are oriented in predetermined directions (by rubbing), and at least one of the first and second alignment films is at least partly treated such that its surface condition is changed in order to restrain movement of the liquid crystal molecules (by UV irradiation).
