Abstract

A liquid crystal display device including a liquid crystal layer sealed between a pair of substrates; an alignment layer formed on at least one of the substrates; a polymer formed of a photopolymerized material on the alignment layer; and a pixel electrode, including an electrode portion and a plurality of slits, formed on one of the substrates. The device also includes a source electrode and a Cs intermediate electrode, having the same potential as the pixel electrode, formed between the pixel electrode and one of the substrates; and a Cs bus line located between the Cs intermediate electrode and one of the substrates. The source electrode is formed along a first liquid crystal domain boundary, between the pixel electrode and one of the substrates. The liquid crystal layer contains part of a photopolymerizable monomer, which is a source material of the photopolymerized material.
