Display device
A display device is disclosed, which includes: a substrate having a first edge, wherein the first edge is parallel to a first direction, and the substrate has a display region and a border region adjacent to the display region; a first insulating layer disposed on the substrate; a first electrode layer disposed on the first insulating layer; and a second insulting layer disposed on the first electrode layer, wherein the second insulating layer comprises plural protrusions, the protrusions are disposed in the border region, and the protrusions are arranged along the first direction.
1. A display device, comprising:
a substrate having a first edge, wherein the first edge is parallel to a first direction, and the substrate has a display region and a border region adjacent to the display region;
a first insulating layer disposed on the substrate;
a first electrode layer disposed on the first insulating layer;
a second insulating layer disposed on the first electrode layer, wherein the second insulating layer comprises plural protrusions, the protrusions are disposed in the border region, and the protrusions are arranged along the first direction; and
a bump disposed in the border region and adjacent to one of the plural protrusions, wherein the first electrode layer comprises a hole overlapping the bump;
wherein the first insulating layer comprises a trench disposed in the border region.
2. The display device of claim 1 , wherein the protrusions are protruded toward the display region.
3. The display device of claim 1 , wherein the protrusions are protruded away from the display region.
4. The display device of claim 1 , wherein the protrusions are arranged in a comb shape along the first direction.
5. The display device of claim 1 , wherein the protrusions comprise curve segments.
6. The display device of claim 5 , wherein the second insulating layer further comprises a linear segment disposed between two adjacent curve segments.
7. The display device of claim 1 , wherein the trench is extended along the first direction.
8. The display device of claim 1 , further comprising a second electrode layer disposed on the second insulating layer, wherein a portion of the second electrode layer overlaps a bottom of the trench.
9. The display device of claim 1 , wherein the second insulating layer is not disposed in the trench.
10. The display device of claim 1 , wherein the protrusions comprises a first protrusion and a second protrusion, the first protrusion has a first width in the first direction, a gap between the first protrusion and the second protrusion has a second width in the first direction, and the first width is different from the second width.
11. The display device of claim 10 , wherein the first width is less than the second width.
12. The display device of claim 1 , wherein the bump and the one of the plural protrusions respectively comprise a same material.
13. The display device of claim 12 , wherein the bump is disposed on the first insulating layer.
14. The display device of claim 12 , wherein the bump is disposed at a protruding direction of the one of the plural protrusions.
15. The display device of claim 1 , further comprising plural bumps disposed on the first insulating layer, wherein the bumps are disposed in the border region, and the bumps are arranged in a two dimensional array.
16. The display device of claim 15 , wherein the trench is disposed between two adjacent bumps.
17. The display device of claim 15 , wherein the trench is disposed between the protrusions and the bumps.
18. The display device of claim 1 , wherein a protruding direction of one of the protrusions is a second direction perpendicular to the first direction.
