A method for fabricating liquid crystal (LC) alignment includes the steps of processing an alignment film having a plurality of liquid crystal molecules with a single or plurality of plasma generating devices, such that the liquid crystal molecules are aligned at a high pretilt angle. Compared with the prior art, the present invention is suitable for modifying the alignment film surface adjustablely in directions and angles, and can attain the effect of alignment stability with a high pretilt angle in a single process, thus overcoming the drawbacks of the prior art.
