Abstract

A display device includes: a substrate; a pair of partition walls above the substrate; a light-emitting portion above the substrate that includes a first electrode, a second electrode, and a light-emitting layer located between the first electrode and the second electrode, the second electrode and the light-emitting layer located between the pair of partition walls; and a pixel circuit for applying a voltage to the first electrode. Each of the pair of partition walls includes a conductive portion and an insulating portion that covers side surfaces of the conductive portion for insulating the first electrode and the light-emitting layer from the conductive portion. The second electrode covers an upper surface of the conductive portion of each of the pair of partition walls and is electrically connected to the pixel circuit via the conductive portion.
