摘要：
An object of the present invention is to provide a liquid crystalline polyester resin composition to produce a molded article without generating black foreign materials even if exposed to high temperature. This object is achieved by providing a liquid crystalline polyester resin composition comprising a liquid crystalline polyester and at least one phosphite compound of the formula (I): wherein, R1 represents a hydrogen atom or, an alkyl group having 1 to 4 carbon atoms or a phenyl group, and R2 represents an alkyl group having 1 to 4 carbon atoms or a phenyl group.
