ABSTRACT:
This invention provides a liquid crystal display device which can contribute to the stabilization of alignment of a liquid crystal and can improve the response speed. The liquid crystal display device comprises a pair of substrates and a liquid crystal layer held between the substrates. At least one of the pair of substrates has a polymer on its surface in contact with the liquid crystal layer. The surface shape of the polymer is in a substantially saw form as viewed from the cross-sectional direction of the substrate. The inclination azimuth of the inclination surface of the polymer is substantially the same as the liquid crystal alignment upon the application of the voltage. Preferably, the surface of the polymer has an approximately wedge shape as viewed from the vertical direction of the substrate, and the azimuth of the apex is approximately opposite to the liquid crystal alignment upon the application of the voltage.
