[0200] Performance Test 26 The properties of the liquid crystal compositions of Examples 26-1 to 26-4 and Comparative Example 26 are shown in Table 26-2: Table 26-2

[0201] As can be seen from performance tests 1 to 26, the physical performance parameters of the liquid crystal compositions in each set of examples and comparative examples are basically the same. However, the reliability of the liquid crystal compositions in the examples is 1% to 5% higher than that in the comparative examples (in terms of VHR value). This indicates that the liquid crystal compositions using deuterated thiophene monomers have better reliability than those using non-deuterated thiophene monomers. Furthermore, the more hydrogen atoms of the thiophene monomers used in the liquid crystal compositions are deuterated, the better the reliability.

[0202] In summary, the liquid crystal composition containing highly reliable thiophene monomers provided by this invention exhibits superior reliability and can effectively improve issues such as image retention in liquid crystal displays. Therefore, in addition to possessing the advantages of traditional liquid crystal compositions containing thiophene monomers, such as low rotational viscosity and fast response time, the liquid crystal composition provided by this invention can significantly improve the reliability of liquid crystal materials, thereby reducing the probability of image retention problems in liquid crystal panels.
