Abstract:
1. A liquid crystal display having a plurality of pixel regions arranged in a matrix, the liquid crystal display comprising: a first substrate and a second substrate processed for vertical alignment; a liquid crystal layer sandwiched between the first substrate and the second substrate, the liquid crystal layer including liquid crystal molecules aligning in a direction generally perpendicular to a principal surface of the first substrate when no substantial electric field is applied to the liquid crystal layer; a regulating structure including a bending portion provided on at least one of the first and second substrates for regulating orientation of the liquid crystal layer such that the liquid crystal molecules are aligned obliquely when a voltage is applied so that the orientation will include a plurality of directions; a pixel electrode in each of the pixel regions; a first capacitor electrode in each of the pixel regions, the first capacitor electrode having a main body and an extending portion extending outwardly from one side of the main body; a second capacitor electrode in each of the pixel regions, the second capacitor electrode having a main body of the second capacitor electrode and an extending portion extending outwardly from one side of the main body of the second capacitor electrode, the extending portion of the second capacitor electrode being formed at a location corresponding to a triangular area of the pixel region defined by the bending portion of the regulating structure and an edge of the pixel electrode adjacent to the bending portion of the regulating structure, wherein the angle included between the regulating structure and the edge of the pixel electrode is less than 90 degrees, and the main body of the second capacitor extends outwardly from the triangular area in a first direction and the extending portion of the second capacitor extends in a second direction not parallel to the first direction; an interconnecting portion defining an interconnecting portion area in each of the pixel regions, the interconnecting portion electrically coupling the second capacitor electrode and the pixel electrode such that the second capacitor electrode and the pixel electrode together functions as a counter electrode to the first capacitor electrode; and a plurality of spacers for maintaining a cell gap between the first and second substrates, the plurality of spacers being disposed in a disposed spacer region corresponding to the triangular area of the pixel region and mitigating dark-state light leakage, the disposed spacer region is within the triangular area, and wherein the disposed spacer region is different from the interconnecting portion area.
