    摘要: Novel optically active tolan derivative represented by the general formula (I) and process for preparing thereof;
    (wherein all the symbols are the same as defined in the appended claims) are disclosed. These are effective for use in preparation of liquid crystal material capable of effectively preventing the formation of the cross-­talk phenomenon due to changes due to temperature in the high level multiplexing driving system.

    摘要: An optically active benzoic ester derivative represented by the general formula:
    wherein R represents a straight chain alkyl group having from 1 to 20 carbon atoms; R' represents a straight chain alkyl group having from 2 to 8 carbon atoms; rings A and B each represents
    or a trans-1,4-cyclohexane ring; n represents 0 or 1; and C represents an asymmetric carbon atoms. The compounds of formula (I) are capable of providing a chiral nematic liquid crystal composition having a short spiral pitch when added to a nomatic liquid crystal composition in a small amount and are useful in the production of SBE display devices having excellent performances in a high level multiplexing driving system.
