Abstract

The liquid crystal display device of this invention includes a pair of substrates and a liquid crystal layer including liquid crystal molecules having a negative dielectric anisotropy interposed between the pair of substrates, vertical alignment layers being formed on surfaces of the pair of substrates in contact with the liquid crystal layer, a voltage being applied across the liquid crystal layer by voltage application means formed on the pair of substrates, the liquid crystal molecules being oriented substantially vertical to the pair of substrate when no voltage is applied, wherein a plurality of column structures are provided so as to be at least partly in contact with the pair of substrates, and the liquid crystal layer has a plurality of liquid crystal domains in a direction in the plane of the substrates, and, when a voltage is applied, orientation directions of the liquid crystal molecules are continuous in each of the liquid crystal domains, while the orientation directions of liquid crystal molecules are random among the liquid crystal domains.
