Abstract
The present invention relates to a luminescent device having a plurality of organic EL (Electroluminescence) elements in which at least a charge injection layer and a light-emitting layer are interposed between a pair of electrodes. It is a luminescent device in which plural sets of anodes and cathodes are arranged opposite to each other, and the charge injection layer and the light-emitting layer are formed between these anodes and cathodes, whereby a plurality of the organic EL elements can be controlled independently luminescence. The conductivity &sgr; of the charge injection layer is set such that a leakage current from the organic EL element is 1/100 or less of the current passed through the organic EL element.
