Title: Large EL panel and manufacturing method therefor

Abstract: A manufacturing method is disclosed for a large EL panel in which a plurality of EL display panels are used. Each of said plurality of EL display panels are constructed of an EL display device and a sub-transparent substrate. The EL display device includes a base layer over which a luminescent material is applied, an electrode layer which is laminated on one side of said base layer, and a TFT layer including a circuit section. The circuit section of a TFT layer is disposed behind an adjacent EL display device. Thus, the EL display devices appear to be unified, forming a large EL display panel. In addition, in the case of in which a plurality of EL display devices are arranged in a matrix pattern, pitch between the pixels provided in the pixel section of the TFT array is maintained constant.
