Abstract: A display panel includes a base layer, a pixel defining film on the base layer and including an inorganic material, a bank layer on the pixel defining film and having a plurality of pixel openings, a plurality of light-emitting elements respectively located in the plurality of pixel openings, each of the plurality of light-emitting elements including an anode, a light-emitting pattern, and a cathode, the cathode being in contact with the bank layer, and a lower encapsulation pattern on the bank layer and including a portion on the bank layer. The lower encapsulation pattern includes a first lower encapsulation pattern on the cathode and the bank layer, the first lower encapsulation pattern including a first material, and a second lower encapsulation pattern on the first lower encapsulation pattern, the second lower encapsulation pattern including a second material different from the first material, and a tip portion.

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.
