Abstract
Provided is a liquid crystal polyester resin composition, which comprises 5-20 parts by weight of glass fiber having a specific number average fiber diameter and fiber length after molding and 100 parts by weight of a specific liquid crystal polyester resin, and the flexural modulus thereof measured with using a test piece of 0.5 mm thickness is 25 GPa or more; and also provided a process for producing a molded article therefrom. The liquid crystal polyester resin composition is low in specific gravity, and is excellent in processability, mechanical properties, and heat resistance.
