Abstract
The present invention relates to a method for fabricating an LCD. The method includes fabricating a MAV layer on a glass substrate. The step of fabricating the MAV layer on the glass substrate comprises the steps of: (A) coating MAV organic monomers on the glass substrate; (B) patterning the MAV organic monomers through a photomask; and (C) curing the patterned MAV organic monomers. In accordance with a photo-curing material of the MAV layer, the fabricating method of the present invention has simple processes with low technical requirements.
