Polyimide resin and its production method for non rubbing vertical orientation material

摘要

As for this invention, especially, being uniform in regard to the polyimide resin and its production method for the non rubbing vertical orientation material, it is used for the polyimide resin and its production method for the non rubbing vertical orientation material of showing the pre- tilt angle of the 90 in regard to the production method of the divergence diamine compound which can use for the orientation membrane which shows high pre- tilt angle, the polyimide orientation membrane, with non rubbing method.
