An etching device of glass substrate for display is provided to increase smoothness of a surface of a glass substrate by uniformly streaming an etching liquid with overflow type on a top of the glass substrate. An etching device of glass substrate for display comprises an etching space part(100) and an etching liquid supply part(200). A plurality of glass substrates(G) is vertically arranged in the etching space part. A side shielding film(110) and an etching liquid returning bath(120) are included in a side part and a bottom part of the etching space part. The etching liquid supply part comprises a supply tube body(210) and an etching liquid inflow tube(220). The etching liquid inflow tube is installed in a center inside the supply tube body. An etching liquid is uniformly filled with a space inside the supply tube body through the etching liquid inflow tube.
