Abstract
A thin-film EL display panel which has excellent packageability, high reliability and stable performance characteristics, and which can prevent nonuniformity of brightness and color from occurring and a fabrication method thereof are provided. In the above thin-film EL display panel, two thin-film EL elements 1 and 2 formed by sequentially laminating first electrodes 12 and 22, first insulating layers, luminescent layers, second insulating layers and second electrodes 16 and 26 respectively on glass substrates 11 and 21 are laminated into position and connecting terminal portions 12a, 22a, 16a and 26a for connecting the first electrodes 12 and 22 and second electrodes 16 and 26 are formed on the edge portions of the substrates 11 and 21 of the thin-film EL elements 1 and 2. connecting pad portions 17 and 18 which correspond respectively to the connecting terminal portions 22a and 26a of the thin-film EL element 2 are provided on the edge portions on the substrate of the thin-film EL element 1, the connecting pad portions are connected to the connecting terminal portions of the other thin-film EL element via conductive coupling sections 19 and the connecting pad portions and the con…
