Composition for stripping and stripping method |
摘要 |
The present invention provides a stripping composition and a stripping method capable of easily stripping a color resist or an organic insulating film formed on a substrate to reuse the substrate when defects are found during a process of forming the color filter or organic insulating film on the substrate. In one embodiment, the stripping composition includes about 0.5 to about 45 wt % of hydroxide compound, about 10 to about 89 wt % of alkyleneglycolalkylether compound, about 5 to about 45 wt % of alkanolamine compound, and about 0.01 to about 5 wt % of inorganic salt compound. Advantageously, the stripping process can be performed without damaging a thin film transistor of a bottom substrate while removing the color resist or organic insulating film. |
