Abstract

A display device is disclosed. In one aspect, the display device includes a substrate including a display area and a peripheral area adjacent to the display area. The display device also includes a plurality of display elements disposed in the display area. The display device also includes an insulating layer disposed in the display area and the peripheral area, wherein the insulating layer has a non-continuous area disposed in the peripheral area of the substrate.

First claim

What is claimed is:

1 . A display device comprising:
a substrate comprising a display area and a peripheral area adjacent to the display area; a plurality of display elements disposed in the display area; and an insulating layer disposed in the display area and the peripheral area, wherein the insulating layer has a non-continuous area disposed in the peripheral area of the substrate.

2 . The display device of claim 2 , wherein the substrate has an outer boundary a portion of which is indented toward the display area, and wherein the non-continuous area is disposed between the indented portion of the outer boundary and the display area.

3 . The display device of claim 2 , wherein a cross-section of the indented portion has a semicircular shape, the cross-section being parallel to the substrate.

4 . The display device of claim 2 , wherein the outer boundary has a non-indented portion, and wherein the non-continuous area extends along a direction parallel to the non-indented portion of the outer boundary of the substrate.

5 . The display device of claim 1 , wherein the insulating layer comprises a first insulating layer having a first non-continuous area and a second insulating layer having a second non-continuous area and wherein the non-continuous area comprises an overlapping portion in which the first non-continuous area and the second non-continuous area overlap each other in the depth dimension of the display device.

6 . The display device of claim 5 , wherein a side surface of the first non-continuous area of the first insulating layer and a side surface of the second non-continuous area of the second insulating layer form a continuous surface.

7 . The display device of claim 1 , wherein the insulating layer directly contacts an upper surface of the substrate at a portion thereof nearest to the non-continuous area.

8 . The display device of claim 1 , further comprising:
a dummy pad comprising a portion disposed over the substrate and extending in a direction thereof.

9 . The display device of claim 8 , wherein the dummy pad comprises a non-continuous portion.

10 . The display device of claim 9 , wherein the non-continuous portion of the dummy pad at least partially overlaps the non-continuous area in the depth dimension of the display device.

11 . The display device of claim 8 , further comprising:
an additional insulating layer comprising an additional non-continuous area and covering the dummy pad.

12 . The display device of claim 11 , wherein the additional non-continuous area at least partially overlaps the non-continuous area in the depth dimension of the display device.

13 . The display device of claim 11 , wherein a side surface of the non-continuous area of the insulating layer and a side surface of the additional non-continuous area of the additional insulating layer form a continuous surface.

14 . The display device of claim 11 , wherein the dummy pad comprises a non-continuous portion and wherein the additional non-continuous area overlaps the non-continuous area and the non-continuous portion in the depth dimension of the display device.

15 . The display device of claim 14 , wherein a side surface of the non-continuous area of the insulating layer, a side surface of the non-continuous portion of the dummy pad, and a side surface of the additional non-continuous area of the additional insulating layer form a continuous surface at an overlapping portion in which the non-continuous area, the non-continuous portion, and the additional non-continuous area overlap each other.

16 . The display device of claim 1 , wherein the insulating layer is formed of an inorganic material.

17 . The display device of claim 1 , further comprising a protecting layer covering the non-continuous area of the insulating layer.

18 . The display device of claim 17 , further comprising:
a pixel defining film covering a boundary of each pixel electrode of the plurality of display elements, wherein the protecting layer is formed of the same material as the pixel defining film.

19 . The display device of claim 18 , wherein the pixel defining film extends from the display area into the peripheral area and wherein the protecting layer is a portion of the pixel defining film.

20 . The display device of claim 1 , wherein the insulating layer extends into the display area.

21 . The display device of claim 1 , wherein the insulating layer is formed in the display area and the peripheral area, wherein the insulating layer is continuous in the display area and continuously extends from the display area to a border between the display area and the peripheral area.
