An object of the present invention is to provide a liquid crystalline polyester suitable for an injection molding material such as an electric / electronic part which is excellent in moldability with little generated gas and foreign matters, has high strength, and is excellent in fluidity. The composition comprises a p-oxybenzoate unit, a 4,4'-dioxybiphenyl unit, a 1,4-dioxybenzene unit, a terephthalate unit and an isophthalate unit, and has a specific composition ratio and a number average molecular weight. A liquid crystalline polyester having a molecular weight of 1,000 or more, a thermoplastic resin composition comprising the liquid crystalline polyester and another thermoplastic resin, and a liquid crystalline polyester composition comprising the liquid crystalline polyester or the thermoplastic resin composition and a filler.
