A display panel includes a transistor, a light emitting element, a pixel defining layer, a separator, and a sensing electrode. The light emitting elements includes a first electrode, an intermediate layer disposed on the first electrode, and a second electrode disposed on the intermediate layer. The second electrode is electrically connected to the transistor. The pixel defining film is disposed on the first electrode and defines an emission opening above the first electrode. The separator is disposed on the pixel defining film. The sensing electrode is disposed on the separator. The sensing electrode and the second electrode are electrically separated by the separator.

Display panel including sensing electrode and electrode of light emitting element electrically separated by at least one separator and display device including the same

A display device includes a display layer that displays an image, and a sensing layer that is disposed on the display layer and includes a plurality of first sensing electrodes and a plurality of second sensing electrodes intersecting the plurality of first sensing electrodes. The display layer may include a transistor, a light emitting device, which includes a first electrode, an intermediate electrode disposed on the first electrode, and a second electrode disposed on the intermediate electrode, a pixel defining film, in which an emission opening portion overlapping a portion of the first electrode is defined, and a separator which is disposed on the pixel defining film and interrupting a continued formation of the second electrode. The plurality of first sensing electrodes and the plurality of second sensing electrodes may overlap the separator.
