摘要：
The present invention provides novel phenylacetylene compounds, liquid crystal compositions having a large refractive index anisotropy (&Dgr;n), and liquid crystal elements produced with the same. The liquid crystal composition contains at least one compound of formula (3A), and at least one compound selected from the group consisting of compounds of any one of formulae (3B) to (3C), wherein A1 to A12: alkyl group optionally substituted with F; R1, R2: H, F; A13 to A24: H, F; m: 0 or 1; Rings A to D: 1,4-phnylene, 1,4-cyclohexylene; R5, R6: H, F; Z1 to Z3: —COO—, —OCO—; b to d: 0 or 1 with b+c+d□1; B1 to B12: alkyl or alkoxy group; R7, R8: H, F:
