In general, the contribution is larger if the black luminance is reduced.
  • the liquid crystal material is thermally moved to cause light scattering and to decrease the contrast by increasing the black luminance.

  • K 22 is the elastic constant of torsion
  • the liquid crystal composition satisfies ⁇ n, n e and n o while satisfying (it is necessary to set ⁇ n ⁇ d to the value).
  • K is required, and by achieving this, the black luminance of the liquid crystal display element can be reduced and the contrast can be improved.
  • the nematic phase-isotropic liquid phase transition temperature (T NI ) is high, the solid phase-nematic phase transition temperature (T CN ) is low, and excellent low temperature storage stability is essential.
