Abstract
A display apparatus includes a thin film transistor disposed in a display area of a substrate and a display device in the display area that is electrically connected to the thin film transistor, an encapsulation layer that protects the display device, at least one through portion formed in the display area that vertically penetrates the substrate and a plurality of layers stacked on the substrate, and a first groove and a second groove that are spaced apart from each other and that surround the at least one through portion. A flow-restriction portion is disposed in a region between the first groove and the second groove that protrudes upwards from the substrate and confines an organic encapsulation layer of the encapsulation layer.
Claims20
A display apparatus comprising:
- a substrate that includes a display area and a peripheral area outside the display area;
- a thin film transistor disposed in the display area of the substrate;
- a display device disposed in the display area that is electrically connected to the thin film transistor;
- an encapsulation layer that protects the display device;
- at least one through portion formed in the display area and that vertically penetrates the substrate and a plurality of layers stacked on the substrate;
- and
- a first groove and a second groove that are spaced apart from each other and that surround the at least one through portion,
- wherein
- the encapsulation layer comprises a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer sequentially stacked on each other,
- the first groove and the second groove partition a non-display area between the at least one through portion and the display area into a first region between the display area and the second groove, a second region between the first groove and the second groove, and a third region between the first groove and the at least one through portion, and
- a flow-restriction portion is disposed in the second region that protrudes upwards from the substrate that confines the organic encapsulation layer.
A display apparatus, the display apparatus comprising:
- a display area and a peripheral area outside the display area;
- a substrate that includes a first base layer, a first barrier layer, a second base layer, and a second barrier layer sequentially stacked on each other;
- a display device disposed on the second barrier layer in the display area;
- an encapsulation layer disposed on the display device and that protects the display device and extends from the display area into the peripheral area;
- a through portion formed in the display area that penetrates the display device in a thickness direction of the display device;
- a first groove that surrounds the through portion at a position spaced apart from the through portion;
- a second groove spaced apart from the first groove and that surrounds the first groove;
- and
- a flow-restriction portion disposed between the first groove and the second groove that protrudes upwards from the substrate,
- wherein
- each of the first groove and the second groove penetrates the second barrier layer into a portion of the second base layer, and the second groove is filled by an organic encapsulation layer of the encapsulation layer.
A display apparatus, the display apparatus comprising:

- a through portion formed in the display area of the substrate that penetrates the substrate in a thickness direction of the substrate;
- a first groove that surrounds the through portion at a position spaced apart from the through portion;
- a second groove spaced apart from the first groove and that surrounds the first groove;
- and
- a flow-restriction portion disposed between the first groove and the second groove that protrudes upwards from the substrate,
- wherein
- each of the first groove and the second groove penetrates the second barrier layer into a portion of the second base layer,
- the first inorganic encapsulation layer and the second inorganic encapsulation layer contact each other in the first groove, and
- the second groove is filled by the organic encapsulation layer.
