An alignment film for avoiding the degradation of the charge holding rate of a LCD, due to ionic impurity of the liquid crystal materials, and the LCD that is made of the same is disclosed herein.
The alignment film
10
includes derivatives of polyimides or polyamides and low molecular thermosetting resins having a viscosity of 1-3000 Poise within the temperature of 25° C. Through the use of the alignment film
10
produced by the thermosetting resin monomers, the ionic impurity is prevented from contact with the pixel electrode
16
. The performance of the LCD with the alignment film is improved during the test of reliability, even though a liquid crystal material with high dielectric anisotropy is used.
