Abstract

A display apparatus is provided. The display apparatus can include a substrate hole penetrating a device substrate, light-emitting devices spaced away from the substrate hole, and at least one separating device between the substrate hole and the light-emitting devices. Each of the light-emitting devices can include a light-emitting layer between a first electrode and a second electrode. The separating device can surround the substrate hole. The separating device can include at least one under-cut structure. The under-cut structure can include a depth and a length, which are larger than a thickness of the light-emitting layer. Thus, in the display apparatus, the damage of the light-emitting devices due to external moisture permeating through the substrate hole can be prevented.

Dependent claims

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.
