| 摘要 |
The present invention relates to a polyamide-imide precursor composition, of which molecular structure includes: a first block in which monomers including dianhydride and diamine are co-polymerized; and a second block in which monomers including aromatic dicarbonyl compounds and aromatic diamine are co-polymerized, wherein the dianhydride includes biphenyltetracarboxylic dianhydride (BPDA) and 2-bis (3,4-dicarboxyfenyl) hexafluoropropane dianhydride (6FDA), and the diamine includes bis-(trifluoromethyl) benzidine (TFDB). Additionally, the present invention provides a polyamide-imide film which is manufactured by imidization of the polyamide-imide precursor composition, and a display device including the film. |
