A liquid crystal display device with a vertical alignment mode in which a high image quality and a wide viewing angle are secured includes a liquid crystal layer having an initial state of vertical alignment interposed between a pair of substrates opposite to each other. A plurality of alignment control structures including a dielectric protrusion protruded toward the liquid crystal layer from the inner surface of the substrate is provided in a dot area constituting one unit of display. When that the dielectric constant of the dielectric protrusion is epsilont1, the dielectric constant of a major axis direction of liquid crystal molecules constituting the liquid crystal layer is epsilon//, and the dielectric constant of a minor axis direction thereof is epsilon⊥, the dielectric constants satisfy the expression epsilon⊥>epsilon//epsilont1.
