Abstract: A display panel includes a base layer, a circuit element layer, and a light-emitting element layer. The circuit element layer includes a power electrode, and an auxiliary electrode disposed on a side surface of the power electrode. The light-emitting element layer includes a pixel defining film that defines a pixel opening, a conductive partition wall disposed on the pixel defining film, a lower electrode disposed in the pixel opening, a light-emitting pattern disposed on the lower electrode, and an upper electrode disposed on the light-emitting pattern. The conductive partition wall includes a first conductive layer disposed on the pixel defining film, and a second conductive layer, and a side surface of the second conductive layer more protrudes than a side surface of the first conductive layer. The upper electrode is electrically connected to the power electrode via the auxiliary electrode.

Abstract: A display panel which includes a base layer, a pixel defining layer on the base layer and that has a light emitting opening, a barrier wall on the pixel defining layer and that has a barrier wall opening that overlaps the light emitting opening, and a light emitting element including an anode, an intermediate layer, and a cathode that makes contact with the barrier wall. The barrier wall opening includes a first inner surface and a third inner surface that extend in a direction parallel to a first direction, a second inner surface and a fourth inner surface that extend in a direction parallel to a second direction crossing the first direction, a first corner region, a second corner region, a third corner region, and a fourth corner region.
