| 摘要 |
本发明中，藉由含有通式(1)所表示的单元结构及通式(2)所表示的单元结构的聚醯亚胺前驱物，而提供一种与膜的煅烧条件无关而不引起膜的白化、龟裂、发泡的聚醯亚胺前驱物，且提供一种使用上述聚醯亚胺前驱物的可挠性TFT阵列、可挠性彩色滤光片、带有阻气层的可挠性基板及使用该等的可挠性显示装置等。;(通式(1)、通式(2)中，X 1 ~X 4 分别独立地表示氢原子、碳数1~10的一价有机基或碳数1~10的一价烷基矽烷基。R 1 是由通式(3)所表示，R 2 是由通式(4)所表示);(通式(4)中，R 3 及R 4 分别独立地表示碳数1~10的一价有机基) In the invention, a polyimide precursor which does not cause whitening, cracking, and foaming of a film (unrelated with a firing condition of the film) is provided by containing a polyimide precursor of a unit structure represented by General Formula (1) and a unit structure represented by General Formula (2). Also provided are a flexible TFT array using the polyimide precursor, a flexible color filter, a flexible substrate with a gas barrier layer, a flexible display device using the above, etc.;(In General Formula (1) and General Formula (2), X 1 to X 4 respectively and independently represent a hydrogen atom, a monovalent organic group having a carbon quantity from l to 10, or a monovalent alkylsilyl group having a carbon quantity from 1 to 10. R 1 is represented by General Formula (3), and R 2 is represented by General Formula (4)). ;(In General Formula (4), R 3 and R 4 respectively and independently represent a monovalent organic group having a carbon quantity from 1 to 10). |
