Embodiment Construction
[0031] The present invention will be further described in detail below in conjunction with embodiments:
[0032] The parts involved in the following examples are percentages by weight, the temperature unit is °C, and the specific meanings and test conditions of other symbols are as follows:
[0033] S→N represents the transition temperature (℃) from the crystalline state of the liquid crystal to the nematic phase;
[0034] c.p. indicates the clearing point (℃) of liquid crystal, measured by DSC quantitative method;
[0035] γ1 means rotational viscosity (mPa·s), test conditions: 25±0.5°C, 20 micron parallel box, test instrument: INSTEC: ALCT-IR1;
[0036] Δn represents optical anisotropy, △n=n o -n e , Where n o Is the refractive index of ordinary light, n e It is the refractive index of extraordinary light, test condition: 589nm, 25±2℃, test instrument: Abbe refractometer;
[0037] △ε represents dielectric anisotropy, △ε=ε ∥ -ε ⊥ , Where ε ∥ Is the dielectric constant parallel to the ...
