Abstract

A display apparatus includes a substrate on which a central area having a display area and a peripheral area disposed around the central area are defined. The display apparatus includes a display area inorganic layer on the display area and extending to a portion of the peripheral area; and an encapsulation inorganic layer covering the display area, on the display area inorganic layer, and having an edge that is in parallel with or extending over an edge of the display area inorganic layer.

Claims (25)

1 . A display apparatus comprising:

a substrate having a display area and a peripheral area around the display area;

a display device on the display area;

an encapsulating layer covering the display device, and comprising a first encapsulation inorganic layer and a second encapsulation inorganic layer on the first encapsulation inorganic layer;

a first blocking member and a second blocking member disposed on the peripheral area; and

an inorganic insulating layer disposed below the first blocking member and the second blocking member,

wherein the first blocking member is provided in two layers, and the second blocking member is provided in three layers,

wherein the first encapsulation inorganic layer and the second encapsulation inorganic layer is disposed on the first blocking member and the second blocking member, and

wherein a distance from an edge of the substrate to an edge of the inorganic insulating layer is greater than a distance from the edge of the substrate to an edge of the first encapsulation inorganic layer.

2 . The display apparatus of claim 1 , wherein a distance from an edge of the substrate to an edge of the inorganic insulating layer is greater than a distance from the edge of the substrate to an edge of the second encapsulation inorganic layer.

3 . The display apparatus of claim 1 , wherein the first blocking member is disposed closer to the display area than the second blocking member, and a height of the second blocking member is higher than a height of the first blocking member.

4 . The display apparatus of claim 1 , wherein the encapsulating layer further includes an encapsulation organic layer between the first encapsulation inorganic layer and the second encapsulation inorganic layer.

5 . The display apparatus of claim 1 , wherein a distance between the second blocking member and an edge of the substrate is greater than a distance between the second encapsulation inorganic layer and the edge of the substrate.

6 . The display apparatus of claim 1 , wherein the inorganic insulating layer is disposed from the display area to a portion of the peripheral area.

7 . The display apparatus of claim 1 , wherein the inorganic insulating layer directly contacts the first encapsulation inorganic layer in at least a region of the peripheral area.

8 . The display apparatus of claim 1 , wherein the second encapsulation inorganic layer directly contacts the first encapsulation inorganic layer in at least a region of the peripheral area.

9 . The display apparatus of claim 1 , wherein the edge of the first encapsulation inorganic layer is spaced from the edge of the substrate.

10 . The display apparatus of claim 1 , wherein the edge of the first encapsulation inorganic layer extends over the edge of the inorganic insulating layer.

11 . The display apparatus of claim 1 , wherein the first encapsulation inorganic layer directly contacts the substrate in at least a region of the peripheral area.

12 . The display apparatus of claim 1 , wherein a height of the second blocking member is greater than a height of the first blocking member.

13 . The display apparatus of claim 1 , wherein the first blocking member comprises a first layer and a second layer on the first layer, and

the second blocking member comprises a first layer, a second layer, and a third layer sequentially stacked on each other,

wherein the first layer of the first blocking member, and the second layer of the second blocking member comprise the same material.

14 . The display apparatus of claim 1 , further comprising a conductive member disposed below the second blocking member.

15 . The display apparatus of claim 1 , further comprising at least a protective layer on the second encapsulation inorganic layer and terminating at an upper surface of the substrate in the peripheral area of the substrate, wherein a distance between the protective layer and an edge of the substrate is less than a distance between the second encapsulation inorganic layer and the edge of the substrate.
