摘要： 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=+1 of 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.

摘要： One picture element is divided into first and second sub-picture element regions. A sub-picture element electrode connected directly (not via capacitive coupling) to a source electrode of a TFT is placed in the first sub-picture element region and a sub-picture element electrode capacitively coupled to a control electrode connected to a source electrode is placed in the second sub-picture element region. A transparent resin film is formed in the first sub-picture element region and this makes a liquid crystal layer thickness in the second sub-picture element region thicker than that of the first sub-picture element region.
