摘要： A display panel (DP) includes a base layer (BL), a pixel-defining film (PDL) which is disposed on the base layer (BL), and in which a light-emitting opening (OP-E) is defined, a partition wall (PW) which is disposed on the pixel-defining film (PDL), and in which a partition wall opening (OP-P) corresponding to the light-emitting opening (OP-E) is defined, and a light-emitting element (ED) disposed in the partition wall opening (OP-P) and including an anode (AE), an intermediate layer (EP), and a cathode (CE) in contact with the partition wall (PW). The partition wall (PW) includes a first partition wall layer (L1) having first metal including at least one of germanium or copper, aluminium, and nickel, and a second partition wall layer (L2) disposed on the first partition wall layer (L1), and including second metal or a silicon-based compound.
