Liquid crystal display device and methods for producing same with alignment layer having new bond formation or bond cleavage reaction of molecular chains by light irradiation

摘要

A liquid crystal display device includes: a pair of substrates; a pair of electrodes formed on the pair of substrates; a pair of alignment films formed on the pair of electrodes; and a liquid crystal layer sandwiched between the pair of alignment films, wherein at least one of the alignment films have a property of aligning liquid crystal molecules of the liquid crystal layer with a pretilt angle, the property being provided by a new bond formation reaction or bond cleavage reaction of molecular chains caused by irradiating the at least one alignment film with light.
