Assignee: LG DISPLAY CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A method of manufacturing a display panel, the method comprising:
forming, on a mother substrate, a light emitting element including a first electrode, a light emitting layer on the first electrode, and a second electrode on the light emitting layer;
forming a protection layer on the light emitting element formed on the mother substrate to encapsulate the light emitting element;
forming a first self-healing layer containing a first polymer precursor on the protection layer;
forming a second self-healing layer containing a second polymer precursor on the mother substrate;
cutting the mother substrate into a plurality of substrates, each substrate being a component of a display panel; and
forming a sealing layer filling a space between the first self-healing layer and the second self-healing layer with materials resulting from reaction of the first polymer precursor from the first self-healing layer and the second polymer precursor from the second self-healing layer, on at least one vertical surface of a substrate of each of the plurality of substrates, and on at least one vertical surface of the protection layer that is on the same side as the at least one vertical surface of a substrate of each of the plurality of substrates,
wherein the first polymer precursor is different from the second polymer precursor.
