Abstract

A display device and a method of manufacturing the same are disclosed. In one aspect, the display device includes a substrate including a separation area and a plurality of pixel formed over the substrate. The separation area is formed between adjacent pixels, and a plurality of through holes are respectively defined by a plurality of surrounding inner surfaces of the separation area, and wherein each of the inner surfaces passes through the substrate. The display device also includes an encapsulation layer formed over the substrate and covering the inner surfaces of the separation area.

a scan line extending in a first direction while bypassing the cut part; and

a data line extending, while bypassing the cut part, in a second direction crossing the first direction,

wherein the cut part is substantially orthogonal to a direction in which the scan line or the data line extends, and

wherein the cut part has a shape that extends only in one direction, either a first direction or a second direction, in a plan view, in which a length of the cut part is longer than a width of the cut part, the cut part comprises a first cut part along the second direction as a length direction and located between two pixels arranged adjacent to each other in the first direction, and

a second cut part along the first direction as a length direction and located between two pixels arranged adjacent to each other in the second direction, and

a minimum distance between the first cut part and the second cut part is greater than a maximum width of the first cut part.

2 . The display device of claim 1 , wherein the first direction is orthogonal to the second direction.

3 . The display device of claim 1 , wherein the first sub-pixel, the second sub-pixel, and the third sub-pixel respectively emit light of different colors from each other.

4 . The display device of claim 1 , wherein the first cut part and the second cut part are separated from each other.

5 . The display device of claim 1 , wherein, with respect to one pixel among the plurality of pixels, the cut part is provided in plurality to surround the one pixel, and

the one pixel is surrounded by four cut parts comprising the first cut part, the second cut part, a third cut part, and a fourth cut part, which are respectively separated from each other.

6 . The display device of claim 5 , wherein the first cut part is arranged in parallel with the third cut part, and the second cut part is arranged in parallel with the fourth cut part.

7 . The display device of claim 1 , wherein the data line comprises a first data line and a second data line that are adjacent to each other with the cut part therebetween, and

the first data line and the second data line are symmetrically arranged with respect to the cut part.

8 . The display device of claim 1 , wherein the scan line comprises a first scan line and a second scan line that are adjacent to each other with the cut part therebetween, and

the first scan line and the second scan line are symmetrically arranged with respect to the cut part.

9 . The display device of claim 1 , wherein the cut part passes through the substrate.

10 . A display device comprising:

a substrate;

a plurality of pixels formed on the substrate, each of the plurality of pixels including a first sub-pixel, a second sub-pixel, and a third sub-pixel; and

a cut part located between the plurality of pixels and provided to penetrate the substrate,

wherein the plurality of pixels comprise a first pixel and a second pixel, which have different arrangements of the first sub-pixel, the second sub-pixel, and the third sub-pixel from each other, and

the first pixel and the second pixel are alternately arranged in a first direction,

wherein the cut part has a shape that extends only in one direction, either a first direction or a second direction, in a plan view, in which a length of the cut part is longer than a width of the cut part, the cut part comprises a first cut part along the second direction as a length direction and located between two pixels arranged adjacent to each other in the first direction, and

a second cut part along the first direction as a length direction and located between two pixels arranged adjacent to each other in the second direction, and

a minimum distance between the first cut part and the second cut part is greater than a maximum width of the first cut part.

11 . The display device of claim 10 , wherein the cut part is located between the first pixel and the second pixel.

12 . The display device of claim 10 , wherein the first pixel and the second pixel are alternately arranged in a second direction crossing the first direction.

13 . The display device of claim 10 , wherein the first pixel and the second pixel are separated from each other at constant intervals.

14 . The display device of claim 13 , wherein a separation distance between the first pixel and the second pixel is greater than a separation distance between each of the first sub-pixel, the second sub-pixel, and the third sub-pixel.

15 . The display device of claim 10 , wherein the cut part passes through the substrate.

16 . A display device comprising:

a substrate;

a first pixel, a second pixel, a third pixel, and a fourth pixel formed on the substrate and each including a plurality of sub-pixels; and

at least one cut part between the first pixel to the fourth pixel and provided to penetrate the substrate,

wherein the first pixel to the fourth pixel are arranged in a same plane with the at least one cut part therebetween, and

wherein the at least one cut part has a shape that extends only in one direction, either a first direction or a second direction, in a plan view, in which a length of the at least one cut part is longer than a width of the at least one cut part, the cut part comprises a first cut part along the second direction as a length direction and located between two pixels arranged adjacent to each other in the first direction, and

a second cut part along the first direction as a length direction and located between two pixels arranged adjacent to each other in the second direction, and

a minimum distance between the first cut part and the second cut part is greater than a maximum width of the first cut part.

17 . The display device of claim 16 , wherein each of the plurality of sub-pixels has a quadrangular shape having a long side extending in a first direction.

18 . The display device of claim 17 , wherein each of the plurality of sub-pixels has a quadrangular shape having rounded corners.

19 . The display device of claim 16 , wherein all of the plurality of sub-pixels included in each of the first pixel to the fourth pixel are arranged in a same direction.

20 . The display device of claim 16 , wherein the length of the at least one cut part in a first direction is greater than a length of each of the plurality of sub-pixels in a same direction.
