METHOD FOR PRODUCING AN ARRAY SUBSTRATE FOR A LIQUID CRYSTAL DISPLAY DEVICE

摘要

The present invention relates to method for producing an array substrate for a liquid crystal display device, wherein an etching solution composition is used which comprises, with respect to the entire weight of the composition, a) from 5 to 25 percent by weight of hydrogen peroxide (H2O2); b) from 0.1 to 5 percent by weight of sulphuric acid; c) from 0.01 to 1.0 percent by weight of a fluorine-containing compound; d) from 0.1 to 5 percent by weight of an azole compound; e) from 0.1 to 5 percent by weight of an imidazole compound; and f) a balance of water.
