Claim 9:
10. A display device comprising:
a display region including, on a substrate, a thin film transistor (TFT) layer, a light-emitting element layer including a plurality of light-emitting elements, and a sealing layer in this order; and
a frame region around the display region,
wherein the light-emitting element layer further includes:
for each of the plurality of light-emitting elements, a first electrode and a plurality of openings exposing the first electrode,
an edge cover covering an end portion of the first electrode,
a plurality of light-emitting layers covering each of the plurality of openings, and
a second electrode that is common to the plurality of light-emitting elements and covers the plurality of light-emitting layers,

the second electrode includes a metal nanowire,
the light-emitting element layer further includes an auxiliary wiring line in a lattice pattern in a position overlapping the edge cover,
the auxiliary wiring line and the metal nanowire are electrically connected to each other,
the light-emitting element layer further includes an inorganic hole transport layer between the first electrode and each of the plurality of light-emitting layers,
the inorganic hole transport layer that is common to the plurality of light-emitting layers, and
the inorganic hole transport layer is provided on a sealing layer side of the edge cover, and is in contact with the auxiliary wiring line.
