PROBLEM TO BE SOLVED: To provide a liquid composition, capable of producing a liquid crystalline polyester film with high heat conduction, a method for producing a liquid crystalline polyester film, and a liquid crystalline polyester film.SOLUTION: A liquid composition includes: a liquid crystalline polyester including an aromatic hydroxycarboxlic repeating unit represented by formula (1): -O-Ar-CO-; an aromatic dicarboxylic repeating unit represented by formula (2): -CO-Ar-CO-; a repeating unit represented by formula (3): -X-Ar-Y-; and a repeating unit having a group represented by formula (4); and an aprotic solvent (in the formulae, Arrepresents naphthylene, phenylene, biphenylylene or a group represented by formula (4); Arand Areach independently represents phenylene, naphthylene, biphenylylene, a group represented by formula (4) or a group represented by formula (5): -Ar-Z-Ar-; X represents imino or oxygen atom, and Y represents oxygen atom or imino. In formula (4), R represents 1-6C alkyl, and a plurality of R may be the same or different. n is an integer of 3-5, and a is an integer of 0-4. a may be the same or different in a plurality of phenylenes. In formula (5), Arand Areach independently represents phenylene or naphthylene; and Z represents oxygen atom, sulfur atom, carbonyl, sulfonyl or alkylidene). |
