A nematic liquid crystal composition comprising (a) at least one compound of the formula: <IMAGE> wherein R1 is n-CmH2m+1, n-CmH2m+1-O or n-CmH2m+1-CO; R2 is n-CqH2q+1, n-CqH2q+1-O or n-CqH2q+1-CO; m and q are each an integer of 1 to 10 and n is a symbol indicating that carbons are linked linearly, and (b) at least one compound of the formula: <IMAGE> wherein R3 is n-CrH2r+1 or n-CrH2r+1-O; R4 is n-CsH2s+1 or n-CsH2s+1-O; r and s are each an integer of 1 to 10 and n is as defined above, and where necessary (c) at least one nematic liquid crystal compound having positive dielectric anisotropy and/or its homologous compound, and if necessary (d) at least one nematic liquid crystal compound having negative dielectric anisotropy and/or its homologous compound. This liquid crystal composition, when used for a display device, shows excellent properties in that it is oriented with high stability over a wide temperature range, allows wide-range setting of threshold voltage and is small in temperature dependency and quick to respond to the applied voltage.
