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.
Claims12
A method for manufacturing a liquid crystal aligning film comprising:
- preparing a multilayer structure in which a substrate, a conductive layer, a liquid crystal alignment layer, and a passivation film are sequentially provided, wherein the passivation film is in direct contact with the liquid crystal alignment layer and is at least one of polyethylene terephthalate, polyethylene, polyolefin, or ethylene vinyl acetate;
- 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 on the substrate by removing the passivation film with a portion of the liquid crystal alignment layer,
- wherein the pulse laser is irradiated to the liquid crystal alignment layer from the passivation film and a maximum pulse energy of the pulse laser is 50 μJ or more per pulse and 100 μJ or less per pulse.
