Abstract

Provided is a liquid crystalline polyester composition comprising: 100 parts by weight of liquid crystalline polyester comprising monomer unit (1) and/or (2): wherein the amount of monomer unit (1) is less than 40 mol% based on the total monomer units of the polyester, and 10-250 parts by weight of glass fiber having elliptical cross section, wherein the average major-to-minor axis ratio of the cross section is 1.5-6.0 and the average major axis length of the cross section is 10-40 μm. The LCP composition of the invention can provide molded articles with less warpage and high toughness.
