| titleOfInvention | Polyamic Acid, Polyimide Film, Liquid Crystal Film and Liquid Crystal Display Device |
| abstract | The present invention relates to a polyimide film useful for use in electronic materials, a liquid crystal alignment film using the same, a liquid crystal display device having a liquid crystal alignment film, and a polyamic acid used as a raw material of the polyimide constituting the polyimide film.n n n The polyimide used to prepare the polyimide film is based on the total diamine, 1,2-bis (4- (4-aminobenzyl) phenyl) ethane, 1,6-bis (4- (4-amino It is composed of 50 mol% or more of the diamine component having a core structure having a nonpolar group such as benzyl) phenyl) hexane, 1,1-bis (4- (4-aminobenzyl) -phenyl) heptane, tetracarboxylic dianhydride, and If desired, aminosilicon compounds are used as the liquid crystal alignment film. |
