Abstract The surface properties of soluble polyimide with alkyl side chain as alignment layer were studied by contact angle, pretilt angle and thermal property(Tg) measurements. The contact angle before rubbing was higher than after nibbing and lower glass transition temperature (Tg) were obtained for polyimides with longer alkyl side chain. The pretilt angle was affected by alkyl side chain length and glass transition temperature of polyimide. Key Words: polyimidepretilt anglealkyl side chain lengthglass transition temperature
