Abstract: A display device includes a plurality of pixels on a substrate including an insulating surface. Each of the plurality of pixels includes: a transistor above the insulating surface; a planarization film covering the transistor; a pixel electrode above the planarization film and electrically connected with the transistor; an insulating layer filled in a recess located around the pixel electrode between the pixels adjacent to each other; a light-emitting layer covering a surface of the pixel electrode and at least a part of a surface of the insulating layer; and a counter electrode above the light-emitting layer. A distance between a surface of the substrate and a face of the light-emitting layer in contact with the insulating layer is equal to or smaller than a distance between the surface of the substrate and a face of the light-emitting layer in contact with the pixel electrode.

Abstract: A display device, in which self-luminous elements are arranged, prevents a leakage current through a common layer, included in the self-luminous elements and disposed throughout its image display area, from causing adjacent pixels to emit unintended light. An organic EL display device has a bank and a light-emitting element layer. The bank is formed on a substrate and is positioned in the border between first and second pixels adjacent to each other. The light-emitting element layer is deposed to spread over the first pixel, the second pixel, and the bank. A first electrode and a second electrode are formed on both sides of the light-emitting element layer and inject electric charges to the light-emitting element layer. A third electrode is formed in contact with the light-emitting element layer in an area overlapping with the bank 106 and absorbs the leakage current.
