Display panel and manufacturing method for same
A display panel having a display region and a non-display region, the display panel includes: a substrate having at least one first opening; an electronic component disposed on the substrate; a plurality of pads disposed in the non-display region and including a first pad and a second pad are spaced apart from each other in a first direction with the at least one first opening therebetween; and an adhesive layer disposed between the substrate and the electronic component and overlapping the at least one first opening.
1. A display panel having a display region and a non-display region, the display panel comprising:
a substrate having at least one first opening;
an electronic component disposed on the substrate;
a plurality of pads disposed in the non-display region and including a first pad and a second pad spaced apart from each other in a first direction with the opening disposed therebetween without the plurality of pads overlapping the opening; and
an adhesive layer disposed between the substrate and the electronic component.
2. The display panel of claim 1 , wherein the adhesive layer has a first surface exposed through the at least one first opening.
3. The display panel of claim 1 , wherein the substrate includes a bendable part and a non-bendable part disposed in the non-display region,
wherein the opening overlaps the display region in a position in which the non-bendable part and the display region overlap each other.
4. The display panel of claim 1 , further comprising a first bump electrically connected with the first pad and a second bump electrically connected with the second pad,
wherein:
the first bump and the second bump are disposed between the electronic component and the substrate without overlapping the at least one first opening.
5. The display panel of claim 1 , wherein the at least one first opening has a generally circular shape with an average diameter being equal to or greater than about 10 μm and equal to or less than about 1,000 μm.
6. The display panel of claim 1 , wherein the at least one first opening comprises a plurality of openings spaced apart from each other.
7. The display panel of claim 1 , wherein the at least one first opening comprises a single opening having a generally rectangular shape defined by two sets of generally parallel sides.
8. The display panel of claim 1 , further comprising an insulating layer directly disposed on the substrate and having a second opening overlapping the at least one first opening.
9. The display panel of claim 8 , wherein the second opening contains material from the adhesive layer.
10. The display panel of claim 1 , wherein the first pad is closer to the display region than the second pad.
11. The display panel of claim 10 , wherein the at least one first opening is closer to the first pad than to the second pad.
12. The display panel of claim 1 , wherein:
a first distance between the first pad and the at least one first opening is substantially parallel to the first direction; and
the first distance is equal to or greater than about 10 μm and equal to or less than about 100 μm.
13. The display panel of claim 1 , wherein:
a second distance between the second pad and the at least one first opening is substantially parallel to the first direction; and
the second distance is equal to or greater than about 300 μm and equal to or less than about 700 μm.
14. A display panel having a display region and a non-display region, the display panel comprising:
a substrate having at least one first opening;
an electronic component disposed on the substrate;
a plurality of pads disposed in the non-display region and including a first pad and a second pad spaced apart from each other in a first direction with the opening disposed therebetween; and
an adhesive layer disposed between the substrate and the electronic component, wherein the at least one first opening comprises a first region containing material from the adhesive layer and a second region spaced apart from the adhesive layer with the first region therebetween.
15. The display panel of claim 1 , wherein the at least one first opening has a width in a direction substantially perpendicular to the thickness direction of the display panel, the width being equal to or greater than about 10 μm and equal to or less than about 1,000 μm.
16. The display panel of claim 1 , further comprising a protective film disposed on a first surface of the substrate,
wherein the protective film includes a first opening region overlapping the electronic component.
17. The display panel of claim 16 , wherein the first opening region of the protective film overlaps the at least one first opening.
18. The display panel of claim 4 , wherein the first bump overlaps and contacts the first pad and the second bump overlaps and contacts the second pad.
