Abstract

We have presented a special color film with negative optical-birefringence. It can work as color filter and viewing angle extension film of Normally White Twist Nematic Liquid Crystal Displays (NW TN-LCDs). To fabricate such film we synthesized oil-soluble high-performance polyimide (PI) which can be dissolved in the usual organic solvent and shows negative birefringence after lamination. Mixing PI with certain pigment of green, blue and red color in the solvent with suitable proportion individually and laminating on the glass substrate, we obtained color films of good transmission spectrum and suitable chromatic coordinates. The experimental results show that the color filter can work as compensation films of NW TN-LCDs.
