Patent ID: 8289487

Claim:
A liquid crystal display device comprising: a plurality of pixels each including a first electrode, a second electrode opposing the first electrode, and a vertical-alignment type liquid crystal layer provided between the first electrode and the second electrode, wherein, each of the plurality of pixels includes: a rib provided on the first electrode on the liquid crystal layer and a slit formed in the second electrode on the liquid crystal layer; when a voltage is applied across the liquid crystal layer, a liquid crystal domain is formed such that an azimuth direction of tilting of liquid crystal molecules in a region between the rib and the slit is orthogonal to an azimuth direction that the rib and the slit extend; the rib has a side face whose taper angle, at a location where the rib meets the first electrode, relative to a plane of a first substrate supporting the rib, in a cross section which is orthogonal to an azimuth direction that the rib extends, is 18Â° or less, and wherein the rib comprises a material such that a film of the material with a thickness corresponding to a height of the rib has an optical density (OD) value of 0.8 or more.
