According to the liquid crystal glass substrate thinning etching equipment, by inclining the liquid crystal glass substrate, on one hand, one face of the liquid crystal glass substrate can be thinned, on the other hand, etching liquid flows on the surface of the liquid crystal glass substrate, white powdery precipitates and the like generated by reaction are washed, and the surface quality of the thinned liquid crystal glass substrate is improved.
