Therefore, the phase transition temperature of the liquid crystal material determines the operating temperature range of the liquid crystal display device. Table 1 shows the relationship between Relevant liquid crystal material parameters and the characteristics of the liquid crystal display device related to it. Liquid crystal material parameters are mainly clear Point Tp (temperature transition point from liquid crystal phase to isotropic phase), curing point Ts.N (conversion from nematic phase to smectic phase or solid phase) Temperature point), optically anisotropic birefringence On, dielectric anisotropy Oε, elastic constant Kn (splayed elastic constant), K22 (torsional elastic constant), K33 (flexural elastic constant), rotational viscosity y, etc.
Parameter Symbol Typical value Comments
Clearing point Tclp 80°C. Max. operating temperature
Smectic-Nematic ltransition Ts-N - 40°C. Min. operating temperature
Optical anisotropy A n=n//-n L 0.085=1.562-1 .477 Determines optical behavior
Dielectric anisotropy 0 ε=ε//_ε⊥  7=10.5-3.5  IDetermines behavior in electric field
Elastic constants K11K22, K33 10-11  Newton  Important for response time
Rotational viscosity @20°C Y 1 100 mPa s  Important for response time
