Liquid crystal display panel
摘要:
A double-layered super-twisted nematic liquid crystal display panel, comprising a drive cell having a first liquid crystal layer and control electrodes, and a compensator cell having a second liquid crystal layer. In the first aspect, the first and second liquid crystal layers 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.degree.-210.degree., preferably about 180.degree..
