Beschreibung
Zusammenfassung:	A double-layered super-twisted nematic liquid crystal display panel, comprising a drive cell (2) having a first liquid crystal layer (28) and control electrodes (21,22), and a compensator cell (3) having a second liquid crystal layer (34). In the first aspect, the first and second liquid crystal layers (28,34) have the same twist angle in reverse directions and the first liquid crystal layer has a product DELTA n.d of a birefringence DELTA n and a panel thickness d 1.02 - 1.20 times larger than that of the second liquid crystal layer. In the second aspect, the second liquid crystal layer has a twist angle larger than that of the second liquid crystal layer by 150 DEG - 210 DEG , preferably about 180 DEG .
