Abstract:
1. A liquid crystal display comprising: a first substrate having a pixel electrode including one or more electrode units electrically connected to each other in a pixel of the display; a second substrate facing the pixel electrode and having a light shield portion constituted by a metal film, a color separation filter provided at a location corresponding to an opening defined in the pixel electrode as viewed from above, and a common electrode on a surface thereof; and a liquid crystal layer having negative dielectric constant anisotropy sealed between the first substrate and the second substrate, wherein a surface of the common electrode facing at least one-fourth of a non-electrode part at the outer periphery of the electrode unit is at a height of 0.2 μm or more above a surface of the common electrode facing a part of the electrode unit substantially in the middle thereof, wherein the non-electrode part is defined as the area where the pixel electrode is not present, wherein a point-like protrusion for regulating the alignment of a liquid crystal is provided on the common electrode on the second substrate facing the part of the electrode unit substantially in the middle thereof, and wherein the common electrode has a concave portion defining a valley at a surface thereof, wherein a central portion of the valley formed by the common electrode is located so as to face substantially a central portion of the non-electrode part.
