Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing an acrylic copolymer resin for an interlayer insulating film of a TFT-LCD (thin-film transister-liquid crystal display), and the interlayer insulating film of the TFT-LCD using it. SOLUTION: The method for producing the acrylic copolymer resin for the interlayer insulating film of the TFT-LCD comprises a step for purifying a copolymer solution produced by polymerizing, in the presence of a solvent, (i) an unsaturated carboxylic acid, an unsaturated carboxylic anhydride or a mixture thereof, (ii) a styrenic monomer, (iii) an epoxy-based monomer, (iv) an isobornyl-based monomer, and (v) a dicyclopentadiene-based monomer. The acrylic copolymer resin for the interlayer insulating film of the TFT-LCD is produced by using the method and the interlayer insulating film of the TFT-LCD is obtained by applying the acrylic copolymer resin. The developing properties and the heat resistance of the film can be improved and the transmittance also can be improved by applying the acrylic copolymer resin produced by the above method to a positive interlayer insulating film for the TFT-LCD.
