ABSTRACT:
A glass substrate for supporting an electroluminescent (EL) display element comprising two dielectric layers defining a thin film EL layer, and two electrode layers, attached to each of the two dielectric layers is characterized by being composed of barosilicic acid without hydrolytic products thereon. A method for preparing such a glass substrate comprises the steps of preparing a glass substrate composed of borosilic acid, grinding a surface of the glass substrate, and cleaning the surface of the glass substrate without soaking it in an acidic solution, so that the glass substrate is free from formed hydrolytic products on the surface.
