A first substrate provided with a plurality of pixel electrodes is prepared. A bank layer is formed so as to be placed on the periphery of each pixel electrode to define a plurality of pixel regions and contain a metal ion adsorbent. An organic electro-luminescence film is formed so as to be placed on the bank layer and the plurality of pixel electrodes and contain a metal complex which is a compound having a ligand coordinated to a metal ion. A common electrode is formed on the organic electro-luminescence film. The organic electro-luminescence film is formed such that the concentration of the metal ions is decreased above the bank layer by the metal ion adsorbent.
