A method of manufacturing an organic EL display in which organic EL devices are prevented from being promoted in degradation by interfaces that occur between the hole transporting layer and the luminescent layer and between the luminescent layer and the electron transporting layer during the formation of the organic EL devices. Hybridizing such QDIP arrays to supporting electronic circuitry enables the generation of an IR image that could be used for applications such as surveillance, night vision, and search and rescue operations. Both trenches are lined with a diffusion barrier layer, and a first conductive layer is deposited over the diffusion barrier layer.
