Abstract

A display device may include a substrate, pixels, and a crack mitigation structure. The substrate may include a main region, a sub-region, and a bending region. The bending region may be connected between the main region and the sub-region and may include a curved outline section. The pixels may be disposed on the main region. The crack mitigation structure may be disposed on the bending region. A section of the crack mitigation structure may be substantially parallel to the curved outline section.

Claims (19)

1. A method for manufacturing a display device, the method comprising:

forming an insulating layer on a substrate, wherein the substrate comprises a main region and a neighboring region, wherein the neighboring region is directly connected to the main region, wherein the insulating layer comprises a first insulating section and a second insulating section, wherein the first insulating section overlaps the main region, and wherein the second insulating section overlaps the neighboring region;

forming transistors that overlap the first insulating section;

etching at least the second insulating section to form dams, wherein each of the dams comprises a portion of the second insulating section; and

cutting the neighboring region at a location between two of the dams to form a bending region, wherein the bending region comprises a curved outline section, wherein remaining dams of the dams on the bending region are substantially parallel to the curved outline section.

2. The method of claim 1 , further comprising:

forming an insulating film on the portions of the second insulating section; and

etching the insulating film at locations between the portions of the second insulating section.

3. A method for manufacturing a display device, the method comprising:

forming an insulating layer on a substrate, wherein the substrate comprises a main region and a neighboring region, wherein the neighboring region is directly connected to the main region, wherein the insulating layer comprises a first insulating section and a second insulating section, wherein the first insulating section overlaps the main region, and wherein the second insulating section overlaps the neighboring region;

forming transistors that overlap the first insulating section;

etching at least the second insulating section to form dams, wherein each of the dams comprises a portion of the second insulating section;

cutting the neighboring region at a location between two of the dams to form a bending region, wherein the bending region comprises a curved outline section;

forming an insulating film on the portions of the second insulating section;

etching the insulating film at locations between the portions of the second insulating section;

forming a pixel definition layer on remaining portions of the insulating film on the portions of the second insulating section; and

etching the pixel definition layer at locations between the remaining portions of the insulating film, wherein each of the dams comprises a remaining portion of the pixel definition layer.

4. The method of claim 1 ,

wherein the bending region is partially exposed between the remaining dams.
