ETCHING SOLUTION COMPOSITION FOR METAL LAYER AND MANUFACTURING METHOD OF AN ARRAY SUBSTRATE FOR LIQUID CRYSTAL DISPLAY USING THE SAME

摘要

Provided are an etching solution composition for a metal layer and a manufacturing method of an array substrate for a liquid crystal display using the same. The etching solution composition for a metal layer comprises: an oxidizing agent for a metal layer; saccharide; and water. The manufacturing method of an array substrate for a liquid crystal display uses the etching solution composition. Therefore, the present invention provides excellent work safety, etching speed, and storage stability.
