PPROBLEM TO BE SOLVED: To provide a novel compound that can be used as a retardation-increasing agent to be able to provide an optical film with desired retardation without causing the problem of bleeding out. PSOLUTION: A glucose compound is represented by formula (I): wherein, RSP11/SPand RSP12/SPeach independently represent a 1-10C alkyl group or a 2-10C alkenyl group, wherein one CHSB2/SBgroup or two or more non-adjacent CHSB2/SBgroups in the alkyl and alkenyl groups may be replaced by O; LSP1/SPrepresents -OCO-*, -OCHSB2/SB-* (binding to B at the * side), or a single bond; A and B each independently represent a trans-1,4-cyclohexylene group which may be substituted or a 1,4-phenylene group which may be substituted; and RSP13/SPand RSP14/SPeach independently represent a hydrogen atom or a 1-10C acyl group.
