Abstract
The present invention provides a composition comprising a liquid crystal polyester, a white pigment and a glass fiber bundle obtained by bundling glass fibers using a sizing agent comprising a polyurethane having a polyester polyol unit and at least one of an aliphatic diisocyanate unit or an alicyclic diisocyanate unit, wherein the polyester polyol unit is a polyol unit having an aliphatic polyhydric alcohol unit and at least one of an aliphatic polybasic acid unit or an alicyclic polybasic acid unit. The liquid crystal polyester composition can provide a reflective plate having a high reflectivity.
