Abstract
A method for manufacturing a liquid crystal aligning film includes preparing a multilayer structure in which a substrate, a conductive layer, a liquid crystal alignment layer, and a passivation film are sequentially provided, etching one area of the liquid crystal alignment layer by irradiating a pulse laser to the multilayer structure, and exposing one area of the conductive layer by removing the passivation film, wherein the pulse laser is irradiated to the liquid crystal alignment layer from the passivation film. The method is compatible with a continuous process.
