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; the first substrate is provided with a first domain regulating means, 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; the first domain regulating means has a linetype component extended in a first direction and a linetype component extended in a second direction which approximately has a 90 DEG difference with the first direction; the second domain regulating means also includes similar linetype components; when observing in a vertical direction of the first and the second substrates, the linetype components of the first and the second domain regulating means are parallel and alternate arrangement with each other; the azimuths of the orientations of said liquid crystal form 4 regions having approximate 90 DEG difference with each other by the first and the second domain regulating means.
