PURPOSE: To suppress corrosion due to electrolytic corrosion of aluminum. CONSTITUTION: This peeling liquid for a resist for a liquid crystal display device is used to peel a resist 31 on a source electrode 19 and a drain electrode 18 comprising a laminated film of aluminum and metal having high melting point. This peeling liquid is prepared by diluting alcanol amine (Cn H2n =1-NH3 ) and glycoether (R-(OCH2 CH2 )2 -OH) with pure water. By using this peeling liquid, the liquid resistance is increased to increase the polarization resistance so that the corrosion rate determined by the crossing point of the anode polarization curve of aluminum and the cathode polarization curve of the high melting point metal. Thus, electrolytic corrosion of the aluminum can be decreased.
