Zusammenfassung:	The present invention provides a method for fabricating a liquid-crystal-aligning electrode and a method for fabricating a liquid crystal cell using the same. Firstly, a femtosecond laser pulse is generated by a laser pulse generator, wherein the femtosecond laser pulse has a constant pulse width and constant pulse energy. Then, the femtosecond laser pulse is facilitated to hit a focusing lens. The focusing lens focuses the femtosecond laser pulse on the surface of a transparent conductive film to form periodically-distributed nano-strips on the surface of the transparent conductive film. Liquid crystal molecules align in parallel to the nano-strips, therefore the alignment layer is no longer required. The pulse energy on the strips is adequate to break a plurality of metal-oxygen bonds in the transparent conductive film, and then to form a plurality of metal-metal bonds and reduce the resistance of the electrode. The femtosecond laser pulse can reduce the cost and time for fabricating an alignment film witho
