A COMPOSITION FOR REMOVING ORGANIC-INORGANIC HYBRID ALIGNMENT LAYER

摘要

PURPOSE: A composition for eliminating an organic-inorganic hybrid alignment layer is provided to have a powerful removal strength to an organic alignment layer, to be able to effectively remove an alignment layer existing on the surface of a liquid crystal display panel, and to have the anti-corrosion property to the aluminum wiring. CONSTITUTION: A composition for eliminating an organic-inorganic hybrid alignment layer is characterized in comprising (A) an inorganic alkali compound; (B) more than one kind or two kinds of organic solvents; (C) an aliphatic polyhydric alcohol; (D) an anti-corrosive agent; and the residual amount of water. The composition for eliminating an organic-inorganic hybrid alignment layer is characterized in further comprising an organic alkali compound. The composition for eliminating an organic-inorganic hybrid alignment layer is characterized in comprising (A) 0.1-5 weight% of an inorganic alkali compound; (B) 30-80 weight% of more than one kind or two kinds of organic solvents; (C) 10-50 weight% of an aliphatic polyhydric alcohol; (D) 0.0001-1.0 weight% of an anti-corrosive agent; and the residual amount of water.
