Abstract: According to an embodiment of the disclosure, a display device is provided. The display device includes a substrate, and a light emitting element layer on the substrate and including an anode electrode portion, a cathode electrode portion, a light emitting structure electrically connected between the anode electrode portion and the cathode electrode portion, and a pixel defining layer. The light emitting structure includes a first light emitting structure included in a first sub-pixel and a second light emitting structure included in a second sub-pixel adjacent to the first sub-pixel. The pixel defining layer is between the first sub-pixel and the second sub-pixel and includes a separating structure between the first light emitting structure and the second light emitting structure. The cathode electrode portion includes a first cathode electrode including an opaque conductive material and a second cathode electrode including a transparent conductive material.
