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

Claim 0:
1. A display apparatus comprising:
a substrate hole penetrating a device substrate;
a light-emitting device on the device substrate, the light-emitting device spaced apart from the substrate hole; and
at least one separating device between the substrate hole and the light-emitting device, the at least one separating device including a first pattern, at least one narrow pattern and at least one wide pattern, a width of the at least one narrow pattern being smaller than a width of the first pattern and a width of the at least one wide pattern,
wherein the light-emitting device includes a first electrode, a light-emitting layer and a second electrode, which are sequentially stacked,
wherein the at least one narrow pattern and the at least one wide pattern are alternately stacked on the first pattern in this order, so that each of the at least one separating device includes at least one under-cut structure,
wherein a depth and a length of the at least one under-cut structure are larger than a thickness of the light-emitting layer, and
wherein the width of the first pattern is smaller than a width of a lower surface of the at least one wide pattern disposed at an uppermost portion of the at least one separating device.
