    摘要： A recording display medium is provided which can offer a high display contrast and is less likely to cause a lowering of contrast or disappearance of display even in low temperature and high temperature regions. A smectic liquid crystal composition, for use in the recording display medium, and use of the recording display medium are also provided. The liquid crystal composition comprises: at least one member selected from the group constituting of compounds represented by the following general formula (I): ##STR1## wherein R.sup.1 represents an alkyl or alkoxy group having 8 to 18 carbon atoms; and at least one member selected from the group consisting of compounds represented by the following general formulae (II) to (VII): ##STR2## wherein R.sup.2, R.sup.4, R.sup.5, and R.sup.6 represent an alkyl group having 2 to 18 carbon atoms, R.sup.3, R.sup.7, R.sup.8, R.sup.9, and R.sup.10 represent an alkyl or alkoxy group having 2 to 18 carbon atoms, and X represents a halogen atom or an alkyl or alkoxy group having 2 to 18 carbon atoms.
