1 "the PI precursor is cured in air at a temperature lower than 230 oC ponents from thermal degradation dization. To imidize a typical poly the curing is normally conducted under N2 at a temperature higher than 300 oC. However this curing condition is not practical in the actual LCD process. Since one of aims this work pursues is to relate/apply the results in this work to the actual LCD process was employed in this work and the different degree of imidization itself was considered as one of PI? characteris¬ tics. The different imidization characteristics could thus affect the properties of the LC cell as well as the surface energy/polarity of the AL." about 90% imi& (about 90% imi&):
