In an apparatus for etching a glass substrate according to the present invention, impurities that are attached to the surface of a glass substrate, which are formed by assembling a color filter substrate and a TFT substrate provided in the etching bath filled with etchant, are removed by using ultrasonic oscillation generated from an ultrasonic oscillator, by which a glass substrate having uniform thickness and surface is obtained.
