wherein the distance ranges from about 40 μm to about 80 μm;

a plurality of data lines passing through the display area; and

a plurality of connection lines electrically connecting the plurality of data lines to the plurality of pad electrodes.

2. The display device of claim 1 , further comprising a second organic insulating layer on the first organic insulating layer,

wherein the second organic insulating layer extends past the edge of the first organic insulating layer to overlap a part of the integrated circuit.

3. The display device of claim 2 , wherein the second organic insulating layer comprises:

a first portion overlapping the first organic insulating layer; and

a second portion extending past the edge of the first organic insulating layer to overlap a part of the integrated circuit,

wherein a thickness of the second portion is less than a thickness of the first portion.

4. The display device of claim 3 , wherein the second organic insulating layer comprises a connection portion between the first portion and the second portion, the connection portion of the second organic insulating layer comprising a stepped portion, wherein the stepped portion is on a top surface of the first organic insulating layer.

5. The display device of claim 1 , wherein some of the plurality of connection lines overlap the opening of the first organic insulating layer.

6. The display device of claim 3 , further comprising a touch input layer comprising a plurality of touch electrodes and a touch insulating layer in the display area,

wherein the touch insulating layer overlaps the second organic insulating layer.

7. The display device of claim 6 , wherein the touch insulating layer overlaps the second portion of the second organic insulating layer.

8. The display device of claim 6 , wherein the touch insulating layer comprises at least one of an organic insulating material or an inorganic insulating material.

9. The display device of claim 1 , wherein the plurality of sub-pixels emit light by using a light-emitting diode on a substrate,

wherein a part of the first organic insulating layer is between the substrate and the light-emitting diode.

10. A display device comprising:

a display area having a plurality of sub-pixels;
