Abstract

An object is to efficiently manufacture an organic EL display. A circuit substrate 10 in which is set microstructures 12 and which is formed with wiring 14, and a transparent substrate 20 formed with a transparent electrode 21, an emissive layer 25 and a cathode layer 26, are stuck together with the side formed with the wiring 14 and the side formed with the cathode layer 26 facing the inside, to thereby manufacture an organic EL display 30. In the sticking together of the circuit substrate 10 and the transparent substrate 20, an anisotropic conductive paste or an anisotropic conductive film can be used.
