Abstract
An element division liquid crystal display device with a liquid crystal inserted between first and second plates having alignment films, respectively. The alignment film of at least the first plate includes a single layer of alignment material having a plurality of first and second adjacent domains A and B and is continuously rubbed in one direction through first and second minute domains A and B. A further treatment, different from a rubbing treatment, is effected to the single alignment layer so that a pretilt angle of the liquid crystal contacting the alignment layer at one of the first and second domains is different from the pretilt angle of the liquid crystal contacting the alignment layer at the other domain. The further treatment includes one of the steps of irradiating with UV light, changing the chemical components of the material of the alignment layer, heating or changing the precuring process.
