    • An object of the present invention is to produce a liquid crystal polyester film having excellent thermal conductivity in a thickness direction. Provided is a liquid crystal polyester film, which comprises casting a liquid composition containing a liquid crystal polyester and a solvent; removing the solvent; raising a temperature from 150° C. or lower to a temperature between a liquid crystal transition temperature and 80° C. above the liquid crystal transition temperature of the liquid crystal polyester at a rate of 1.0° C./minute or more; and heat-treating the obtained film at a temperature between the liquid crystal transition temperature and 80° C. above the liquid crystal transition temperature of the liquid crystal polyester. It is preferred to use, as the liquid crystal polyester, those having a liquid crystal transition temperature of 320° C. or lower.
    • 本发明的目的是制造在厚度方向上具有优异导热性的液晶聚酯膜。 本发明提供一种液晶聚酯膜,其包括浇铸含有液晶聚酯和溶剂的液体组合物; 除去溶剂; 使液晶聚酯的液晶转变温度高于液晶聚酯的1.0℃/分钟以上的温度从150℃以下升温至液晶转变温度至80℃以上的温度; 在液晶聚酯的液晶转变温度以上的液晶转变温度和80℃之间的温度下对所得膜进行热处理。 作为液晶聚酯,优选使用液晶转变温度为320℃以下的那些。
