A liquid crystal display device is provided which comprises a first substrate and a second substrate for sandwiching a liquid crystal having a negative dielectric constant anisotropy, and orientations of the liquid crystal are vertical to the first and the second substrates when no voltage being applied, characterised in that the first substrate is provided with a first domain regulating means for regulating azimuths of the orientations of said liquid crystal when a voltage is being applied to said liquid crystal; and the second substrate is provided with a second domain regulating means for regulating azimuths of the orientations of said liquid crystal when a voltage is being applied; a plurality with different orientations in each pixel are formed by the first and sencond domain regulating means; the first domain regulating means is composed of dielectric protrusions seated on an electrode and extending in a line direction; the protrusions is formed by materials for reducing the electric field of a liquid crystal layer on the protrusions; and the second domain regulating means is composed of a line-type domain regulating means extended in parallel with the protrusions.
