1. A display device comprising:

  • a substrate;

    a plurality of partition walls formed on the substrate for separating pixels;

    a light-emitting portion constituting the pixels, in which a first electrode, a light-emitting layer, and a second electrode are stacked in this order between a pair of partition walls among the plurality of partition walls; and

    a pixel circuit for applying a voltage to the first electrode,wherein at least some of the plurality of partition walls includes a conductive portion formed on the substrate in the vertical direction with a conductive material, and an insulating portion covering peripheral side surfaces of the conductive portion with an insulating material,wherein the first electrode and the light-emitting portion are insulated by the insulating portion from the conductive portion, andwherein the second electrode is stacked to cover the conductive portions exposed at the upper surfaces of the partition walls, and is electrically connected to the pixel circuit via the conductive portion.
