An organic electro-luminescence display element comprising: at least a positive electrode; an organic luminescent film; an electron injection layer and a negative electrode, wherein: each of the positive and negative electrodes is formed of a transparent conductive film; the electron injection layer is formed of a thin film having transparency and made of organic metal salt containing alkali metal or alkaline earth metal as the metal, halogenide of alkali metal or alkaline earth metal, or organic metal complex containing alkali metal or alkaline earth metal as the metal; and the organic metal complex is at least one selected from the group consisting of acetylacetonate complex, alpha-nitroso-beta-naphthol complex, salicylaldoxime complex, cupferron complex, benzoinoxime complex, bipyridine complex, phenanthroline complex, crown complex, proline complex and benzoylacetone complex. An organic electro-luminescence display element comprising at least a positive electrode, an organic luminescent film and a negative electrode, wherein the positive electrode is formed of an electrically conductive film having transparency, the negative electrode is formed of a metal film containing metal having a low work function, and the negative electrode is connected to a power supply lead portion made of a transparent and conductive film.
