Abstract
A method for manufacturing ultra-thin glass substrates and a method for manufacturing a display panel are provided. The method for manufacturing ultra-thin glass substrates includes: providing a glass base material preset with n substrate areas and a skeleton area surrounding the substrate areas; at least forming an etching protection layer on each substrate area of the glass base material; immersing the glass base material in a reaction chamber having etching medium; after the edge of each substrate area is etched to form the stress dissipation edge and the substrate areas are separated from the glass base material, the substrate areas falling down by gravity and falling into the basket; pulling the basket out of the reaction chamber to get the substrate areas separated from the glass base material; removing the etching protection layer to get independent glass substrates.
