Abstract

A display device includes: a substrate including an opening defined therein, a display area adjacent to the opening, and a non-display area extended along the opening to be disposed between the opening and the display area; a display element with which an image is displayed, on the substrate in the display area thereof; and a metal layer including a plurality of segments spaced apart from each other, each segment disposed in the non-display area of the substrate.

First claim

What is claimed is:

1 . A display device comprising:
a substrate including a first area, a second area adjacent to the first area, and a third area between the first area and the second area; a display element with which an image is displayed, on the substrate in the second area thereof; and a metal layer including a plurality of segments spaced apart from each other, each segment disposed in the third area.

2 . The display device of claim 1 , wherein the metal layer includes a metal having a light-blocking characteristic.

3 . The display device of claim 1 , wherein the plurality of segments are spaced apart from each other along an outer edge of the first area.

4 . The display device of claim 1 , further comprising a signal wiring portion being in the third area, the signal wiring portion interposed between the metal layer and the substrate.

5 . The display device of claim 4 , further comprising a scan signal line or a data signal line connected to the display element in the second area,
wherein the scan signal line or the data signal line extends from the second area to dispose a portion of the scan signal line or the data signal line in the third area, and the portion of the scan signal line or the data signal line in the third area defines the signal wiring portion in the third area.

6 . The display device of claim 1 , further comprising an input sensing layer on the display element, the input sensing layer including:
first sensing electrodes arranged along a first direction, and second sensing electrodes arranged along a second direction which intersects with the first direction.

7 . The display device of claim 6 , wherein
the metal layer and the first sensing electrodes are respectively portions of a same material layer, or the metal layer and the second sensing electrodes are respectively portions of a same material layer.

8 . The display device of claim 6 , wherein the plurality of segments of the metal layer include:
a first segment electrically connected to one of the first sensing electrodes; and a second segment electrically connected to one of the second sensing electrodes.

9 . The display device of claim 8 , wherein, the first segment of the metal layer is closer to the first sensing electrode than the second sensing electrode.

10 . A display device comprising:
a substrate including a display area in which are defined:
an opening; and
a non-display area between the opening and the display area;
a plurality of display elements in the display area and including a first display element and a second display element which are spaced apart each other with the opening therebetween; a signal wiring in the non-display area, the signal wiring electrically connected to the first and second display elements; and a metal layer in the non-display area.

11 . The display device of claim 10 , wherein the metal layer at least partially overlapping the signal wiring in the non-display area.

12 . The display device of claim 10 , wherein the metal layer includes a plurality of segments arranged spaced apart from each other along an outer edge of the opening.

13 . The display device of claim 10 , further comprising an input sensing layer on the display elements, the input sensing layer including:
first sensing electrodes arranged along a first direction, and second sensing electrodes arranged along a second direction which intersects with the first direction.

14 . The display device of claim 13 , wherein
the metal layer and the first sensing electrodes are respectively portions of a same material layer, or the metal layer and the second sensing electrodes are respectively portions of a same material layer.

15 . A display device comprising:
a substrate including a display area in which are defined:
an opening; and
a non-display area between the opening and the display area;
a plurality of display elements in the display area; an input sensing layer on the display elements; and a metal layer in the non-display area.

16 . The display device of claim 15 , wherein
the input sensing layer includes:
first sensing electrodes arranged along a first direction, and
second sensing electrodes arranged along a second direction which intersects with the first direction, and
the metal layer includes a segment in the non-display area, the segment connected to one of the first sensing electrodes or one of the second sensing electrodes.

17 . The display device of claim 16 , wherein the metal layer includes a plurality of segments in the non-display area.

18 . The display device of claim 17 , wherein
a first sensing electrode among the first sensing electrodes and a second sensing electrode among the second sensing electrodes are arranged adjacent to each other along the opening, the plurality of segments of the metal layer includes:
a first segment connected to the first sensing electrode, and
a second segment connected to the second sensing electrode.

19 . The display device of claim 17 , wherein the plurality of segments are spaced apart from each other along an outer edge of the opening.

20 . The display device of claim 15 , wherein the metal layer and the input sensing layer are respective portions of a same material layer.
