Abstract
A substrate includes an active area and a non-active area, the non-active area including a pad area; a light-emitting element layer disposed on the active area; an encapsulation layer disposed to cover the light-emitting element layer; and one or more pad electrodes disposed on the pad area. A plurality of protrusions are formed on a surface of the pad electrode. A residual organic material is positioned on a portion of the pad area. Since a plurality of protrusions are formed on the surface of a pad electrode, surface adhesion of an organic layer that can be deposited on the surface of the pad electrode can be reduced, a pad open process can be easily performed to expose the surface of the pad electrode to the outside.
Claims20
A display apparatus comprising:
- a substrate including an active area and a non-active area, the non-active area including a pad area;
- a light-emitting element layer disposed on the active area;

- and
- a pad electrode disposed on the pad area,
- wherein a surface of the pad electrode includes a plurality of protrusions, and
- a residual organic material is positioned on a portion of the pad area.
A method of manufacturing a display apparatus, comprising:
- providing a substrate including an active area and a non-active area, the non-active area including a pad area;
- forming a circuit part and a plurality of insulating layers on the substrate of the active area;
- forming one or more pad electrodes including a plurality of protrusions on a surface of the substrate of the pad area;
- forming a light-emitting element layer and a dummy light-emitting element layer on the substrate of the active area and the pad area, respectively;
- forming an encapsulation layer to cover the light-emitting element layer and the dummy light-emitting element layer;
- and
- removing the dummy light-emitting element layer and the encapsulation layer on the pad electrode.
