Provided is a liquid crystal display device of VAIPS mode, which uses a liquid crystal material having negative dielectric anisotropy (DeltaE<0), and has a high response speed, a wide viewing angle, a high transmittance at the time of light transmission, a high black level at the time of light blockage, and an excellent contrast ratio. Disclosed is a liquid crystal display device including a first substrate, a second substrate, and a liquid crystal composition layer having negative dielectric constant, which is interposed between the first substrate and the second substrate, the liquid crystal display device being an electro-optical display device which has a plurality of pixels, and in which each of the pixels is independently controllable and has a pair of a pixel electrode and a common electrode, the two electrodes are provided on at least one substrate of the first substrate and the second substrate, and the long axis of the liquid crystal molecules of the liquid crystal composition layer is in a substantial vertical alignment or a hybrid alignment with respect to the substrate surface.
