1. A display panel comprising:
a transistor;
a light emitting element including a first electrode, an intermediate layer disposed on the first electrode, and a second electrode disposed on the intermediate layer and overlapping the first electrode, wherein the second electrode is electrically connected between the first electrode and the transistor;
a pixel defining film disposed on the first electrode and defining an emission opening above the first electrode;
at least one separator disposed on the pixel defining film; and
one or more sensing electrodes that sense a touch interaction with the display panel, at least one of the one or more sensing electrodes being disposed on the at least one separator,
wherein the one or more sensing electrodes and the second electrode are electrically separated by the at least one separator.
