1. A display panel, comprising:
a substrate;
a light emitting element including a first electrode on the substrate, a light emitting layer on the first electrode, and a second electrode on the light emitting layer;
a protection layer on the light emitting element;
a self-healing layer including a first self-healing layer on the protection layer and containing a first polymer precursor, and a second self-healing layer on the substrate and containing a second polymer precursor; and
a sealing layer positioned between the first self-healing layer and the second self-healing layer, on at least one of vertical surfaces formed by the substrate, and on at least one of vertical surfaces formed by the protection layer that is on the same side as the at least one of vertical surfaces formed by the substrate;
wherein materials of the sealing layer are formed resulting from a reaction of the first polymer precursor from the first self-healing layer and the second polymer precursor from the second self-healing layer, and at least partially fill a space between the first self-healing layer and the second self-healing layer, and
wherein the first polymer precursor is different from the second polymer precursor.
