A liquid-crystal display element is provided, having ncharacteristics such as a short response time, a great voltage retention rate, a low threshold voltage, a great contrast ratio, a long life, and a low flicker rate, etc. The liquid-crystal display element includes: an electrode group, formed on either or both of a pair of opposedly disposed substrates; a plurality of active elements, connected to the electrode group; a liquid-crystal alignment film, formed on respective opposed surfaces of the pair of substrates; and a liquid-crystal composition, sandwiched between the pair of substrates, wherein the liquid-crystal composition contains, as a first component, at least one compound selected from a group of compounds represented by formula (1): n n In formula (1), R 1 is alkyl having 1 to 12 carbons; ring A is 1,4-cyclohexylene, 1,4-phenylene or the like; Z 1 is a single bond or the like; X 1 and X 2 are hydrogen or fluorine; Y 1 is fluorine or the like; and a is 1, 2, 3, or 4. |
