Abstract
Embodiments of the present disclosure relate to a display panel and a method of manufacturing the same. A high-reliability display panel with a reduced bezel area or substantially no bezel area and a method of manufacturing the same.
Claims16
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.

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.
