Abstract: A display device, in which self-luminous elements are arranged, prevents a leakage current through a common layer, provided for the self-luminous elements and disposed throughout its image display area, from causing adjacent pixels to emit unintended light. A light-emitting element layer 102 includes a lower layer 102d and a light-emitting layer. The lower layer 102d has carrier mobility and includes a carrier transport layer or a carrier injection layer. The lower layer 102d is stacked on lower electrodes 100 and banks 106. The light-emitting layer is stacked on the lower layer 102d. An upper electrode 62 is disposed on the light-emitting element layer 102 and supplies carriers to the light-emitting element layer 102 together with each lower electrode. A lower layer 102d has a dividing area 112 on the bank. The dividing area 112 prevents carriers from traveling between adjacent pixels through the lower layer 102d.

Abstract: A substrate on which a plurality of pixel electrodes are disposed is prepared. An organic electroluminescent film 22 is formed with the inclusion of a common layer that continuously covers the plural pixel electrodes. A common electrode is formed on the organic electroluminescent film. The common layer is irradiated with an energy ray above areas between the respective adjacent pixel electrodes with the avoidance of irradiation above the plural pixel electrodes. An electric conductivity of the common layer is reduced above the areas between the respective adjacent pixel electrodes, by irradiation of the energy ray. With this configuration, a current leakage can be prevented between the adjacent pixels.
