Transparent polyimide film |
| abstract |
The present invention relates to a transparent polyimide film formed of a polyimide comprising: a first repeating unit (a) derived from 2,2' -bis (trifluoromethyl) -4,4' -diaminobiphenyl (2, 2' -TFDB) and an acid dianhydride; and one or more repeating units (B) selected from the group consisting of a second repeating unit derived from an ether diamine and an acid dianhydride and a third repeating unit derived from a non-fluorinated diamine and an acid dianhydride. |
