Liquid crystal display

Abstract

A liquid crystal display (LCD) includes a first electrode, a second electrode facing the first electrode, and a liquid crystal layer interposed between the first and second electrodes and having a twisted nematic alignment of liquid crystals, wherein rotation viscosity of the liquid crystal layer is 50 mPas-80 mPas, a cell gap, namely, the thickness of the liquid crystal layer, is 2.5 μm-5.0 μm, a voltage difference between the first and second electrodes is 0.2V-8.0V, and a response time can be obtained from the expression 6.78+(rotation viscosity)×0.81+(cell gap)×0.7+(rotation viscosity)×(cell gap)×0.14. The liquid crystal display having the twisted nematic alignment of liquid crystals, has the pitch of the liquid crystal layer within the range of 10 μm to 70 μm, a cell gap, namely, the thickness of the liquid crystal layer, within the range of 3.0 μm to 4.5 μm, and a voltage difference between the first and second electrodes within the range of 0.2V to 6.0V.
