Patent ID: 8593600

Claim:
A method for fabricating a liquid crystal panel comprising: providing first and second mother substrates each having a plurality of panel regions; performing an array process on the first mother substrate to form a plurality of array substrates having a pad part on the panel regions of the first mother substrate; performing a color filter process on the second mother substrate to form a plurality of color filter substrates on the panel regions of the second mother substrate; forming an alignment film on the entire surface of the first and second mother substrates; performing rubbing in a state that the alignment film is formed on the entire surface of the first and second mother substrates; forming seal patterns on an outer edge portion of the color filter substrate of the rubbed second mother substrate, dropping liquid crystal material on the array substrate of the rubbed first mother substrate and then attaching the first and second mother substrates; cutting the attached mother substrates into a plurality of unit liquid crystal panels with the pad part of the array substrate exposed; loading the cut unit liquid crystal panel within a plasma equipment; and removing a portion of the alignment film formed at the exposed pad part of the array substrate of the loaded cut unit liquid crystal panel within the plasma equipment by dry etching using plasma, wherein the dry etching is performed under conditions of a pressure 500 mTorr, RF power 2000 W, O 2 gas 1500 sccm and SF 6 gas 40 sccm for 40 sec to remove the alignment film without damaging the seal patterns.
