METHOD FOR PRODUCING COMPOSITE SUBSTRATE, COMPOSITE SUBSTRATE, AND EL DEVICE COMPRISING THE SAME

摘要

A method for producing a composite substrate in which no projection nor rece ss due to the electrode layer is formed on the insulating layer, no polishing process is required, the composite substrate is simply produced, and high display quality is achieved when the substrate is applied to a thin-film optical device, wherein an electrode paste and an insulating paste are subsequently thickly applied to an insulating base, consequently an electrod e green film and an insulator green film are formed in multiplayer, thus a composite substrate precursor is fabricated, the surface of the precursor is smoothed by press, and the precursor is baked thereby fabricating a composit e substrate. A composite substrate and a thin-film EL device are also disclose d.
