Abstract:
1. A liquid crystal display device comprising: a pair of substrates; a liquid crystal layer provided between the pair of substrates; an alignment layer provided between at least one of the pair of the substrates and the liquid crystal layer; and an alignment sustaining layer for defining a direction in which liquid crystal molecules constituting the liquid crystal layer are inclined, the alignment sustaining layer being provided between the alignment layer and the liquid crystal layer, and formed from a monomer component, the alignment layer containing a polyimide or a polyamic acid, the alignment layer and the alignment sustaining layer being covalently bound to each other such that (i) the polyimide or the polyamic acid has a polymerization initiator functional group having a function of initiating polymerization reaction of the monomer component for forming the alignment sustaining layer, and (ii) the polymerization initiator functional group and the polymerized monomer component are covalently bound to each other.
