A composite substrate includes a substrate, an electrode formed on the substrate, a first dielectric layer of thick film dielectric formed on the electrode, a second dielectric layer formed on the first dielectric layer by a solution coating-and-firing technique, and a buffer layer formed below and/or within the first dielectric layer. The composite substrate keeps the thick-film dielectric layer fully insulating and enables functional thin films formed thereon such as a light emitting layer to perform stable operation, especially stable light emission. An EL panel using the same and a method for preparing the same are also provided.

A high-voltage feed-through capacitor includes: a capacitor element; a grounding metal fitting; an insulating resin; two through conductors; an insulating cover; and an insulating tube. The capacitor element has two separate electrodes on one side and one common electrode on the other side and is mounted on one side of the grounding metal fitting with the common electrode being connected to the same side of the grounding metal fitting. The insulating resin fills a space inside the capacitor element. Each through conductor has a rod-like conductor portion passing through the grounding metal fitting and the capacitor element and connected to the separate electrode. At least a portion of the insulating tube is attached to the rod-like conductor portion within the capacitor element. The insulating cover is attached to the rod-like conductor portion to have one end thereof in contact with one end of the insulating tube.

The invention aims to provide a method for preparing a composite substrate which has minimized surface asperities on a dielectric layer, which are otherwise developed under the influence of an electrode layer, unevenness upon printing, and surface roughness inherent to thick-film dielectrics, which eliminates a need for a polishing step, which is easy to manufacture, and which is applicable to the fabrication of a thin-film light-emitting device of high display quality, as well as the resulting composite substrate and a thin-film EL device using the same. The object is attained by a method for preparing a composite substrate, comprising the steps of forming at least an electrode and a green dielectric layer according to a thick-film technique on an electrically insulating substrate, thereby providing a composite substrate precursor, smoothing the surface of the precursor by WIP process, and firing to complete the composite substrate, as well as the resulting composite substrate and a thin-film EL device using the same.

A thin-film EL device includes a lower electrode layer, a barrier layer containing a conductive inorganic compound, a lower insulating layer, a light emitting layer, and an upper electrode layer stacked in order on an electrically insulating substrate. An EL device of high display quality is established at a low cost by acquiring satisfactory light emitting properties without using an expensive high-melting point noble metal in the lower electrode layer and without increasing the thickness of the lower electrode layer, even when the lower insulating layer contains a lead base dielectric material.
