Abstract: The difference between e1 and e3 parameters for flexoelectric polarization, as originally defined byMeyer, is measured for nematic liquid crystal materials E7 and BL087 in Twisted Nematic (TN) cells with In-Plane Switching (IPS) electric fields using the crystal rotation method, which measures transmission as a function of angle of incidence. Values of e₁ − e₃ for E7 and BL087 are found to be 7.2±1.0 pCm⁻¹ and 9.4±1.0 pCm⁻¹ respectively.
