LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT

WIPO Patent Application WO/2016/152299

A1

The purpose of the present invention is to provide a liquid crystal composition having the appropriate balance in relation to at least one or at least two characteristics from among characteristics such as the following: a high nematic phase upper-limit temperature; a low nematic phase lower-limit temperature; low viscosity; appropriate optical anisotropy; large dielectric anisotropy; large relative permittivity; high stability with respect to ultraviolet rays or heat; and a large elastic constant. A further purpose is to provide an active matrix element that has: a short response time; a large voltage retention rate; a low threshold voltage; a large contrast ratio; a large negative DC luminance relaxation time constant; and a long life. Provided are the following: a liquid crystal composition that has positive dielectric anisotropy, that contains, as an additive component, a compound which contributes to high-stability with respect to heat or ultraviolet rays, and that contains, as a first component, a prescribed compound having low viscosity; and a liquid crystal display element that contains the composition. The composition may contain the following: a prescribed compound which serves as a second component and has large positive dielectric anisotropy; a prescribed compound which serves as a third component and which has a high upper-limit temperature or low viscosity; or a prescribed compound which serves as a fourth component and which has negative dielectric anisotropy.
