Abstract: Quadrangular prism-like EL bars are each formed by depositing a light emitting layer and a positive hole transport layer on an outer surface of a data line. The EL bars are arranged in such a manner that each of the EL bars crosses a plurality of scanning lines formed on a transparent substrate. A sealing substrate presses the EL bars against the scanning lines. A sealing layer is formed along the outer circumference of the sealing substrate and the outer circumference of the transparent substrate. The sealing layer seals the space between the sealing substrate and the transparent substrate (that accommodates the data lines, the light emitting layers, the positive hole transport layers, and the scanning lines). This configuration facilitates design changing of an electroluminescence apparatus including modification of the size of the apparatus, the pixel size, and the type of the functional layers, thus improving productivity.

Abstract: A cathode layer, which is formed along the outer circumferential surface of a support rod, is immersed in light emitting layer forming liquid containing light emitting layer material. The cathode layer is then raised from the light emitting layer forming liquid, thus forming a light emitting liquid film with uniform thickness on the outer circumferential surface of the cathode layer. By drying the liquid film, a light emitting layer with uniform thickness is formed on the entire outer circumferential surface of the cathode layer. The light emitting layer is then immersed in hole transport layer forming liquid. This facilitates changes of the size or the shape of an electroluminescence device, improving productivity for manufacturing the electroluminescence device.
