ABSTRACT:
A vertically aligned liquid crystal display device for controlling liquid crystal molecules alignment with linear structures or slits consisting of a plurality of constituent units on at least one of a pair of substrates. In one configuration, an alignment controlling means forms an alignment singular points s=+1of liquid crystal molecules at an intersecting point between the structures (or slits) and an edge of a pixel electrode. Preferably, at least one of the constituent units has bending portions over a capacitive bus line. In one preferred embodiment, the height of a portion of the linear structure opposite an edge of a pixel electrode is higher than other areas of the linear structures. Additionally, all liquid crystal molecules around an intersecting point between the structures or the slits formed on one substrate and an edge of a pixel electrode formed on the other substrate are preferably aligned to the intersecting point.
