Abstract:
1. A liquid crystal display device comprising: a pair of substrates; and a liquid crystal layer between the substrates, wherein the liquid crystal layer includes liquid crystal molecules having negative dielectric anisotropy, when no voltage is applied to the liquid crystal layer, the liquid crystal molecules are aligned substantially vertically to surfaces of the substrates and being slightly tilted to a first alignment direction, a second alignment direction which is different by approximately 90° from the first alignment direction, a third alignment direction which is different by approximately 180° from the first alignment direction, or a fourth alignment direction which is different by approximately 270° from the first alignment direction, wherein the liquid crystal display device comprises a first pixel and a second pixel adjacent to the first pixel, each of the first pixel and the second pixel is divided into four or more alignment regions as viewed in a plan view of a main surface of one of the substrates, wherein of the four or more alignment regions include a first alignment region in which the liquid crystal molecules are tilted to the first alignment direction, a second alignment region in which the liquid crystal molecules are tilted to the second alignment direction, a third alignment region in which the liquid crystal molecules are tilted to the third alignment direction, and a fourth alignment region in which the liquid crystal molecules are tilted to the fourth alignment direction, the first pixel includes a first unit, the second pixel includes a second unit which is located at same vertical and horizontal position as the first unit, and a third unit which is located at symmetric position of the first unit with respect to a border between the first pixel and the second pixel, an alignment direction of the first unit is different from an alignment direction of the second unit, and the alignment direction of the first unit is same as an alignment direction of the third unit.
