摘要
PURPOSE: An etching and cleaning solution for glass in liquid crystal display devices and etching method using the same are provided to facilitate etching speed control, thereby producing a glass substrate with desired thickness. CONSTITUTION: An etching and cleaning solution for glass in liquid crystal display devices comprises 0.1-30wt% fluoride salt, 10-60wt% inorganic acid, 0.001-3wt% surfactant, and the remainder of water. The fluoride salt is ammonium fluoride(NH4F), ammonium bifluoride(NH4HF2), potassium fluoride(KF), or lithium fluoride(LiF). The inorganic acid is nitric acid or sulfuric acid.
