Display device
A display device includes a first substrate including a first area, a second area, and a bending area that is between the first area and the second area, and including a second inclined surface facing the bending area, a light-emitting element at the first area, and a first bending-protection layer at the first area and the second area, not overlapping the bending area, and including a first inclined surface facing the bending area and aligned with the second inclined surface.
1 . A display device comprising:
a first substrate comprising a first area, a second area, and a bending area that is between the first area and the second area, and comprising a second inclined surface facing the bending area;
a light-emitting element at the first area;
a first bending-protection layer overlapping the bending area; and
a second bending-protection layer at the first area and the second area, not overlapping the bending area, and comprising a first inclined surface facing the bending area and aligned with the second inclined surface.
2 . The display device of claim 1 , wherein the first second bending-protection layer comprises a first portion and a second portion spaced apart from each other with the bending area interposed therebetween, the first portion comprising the first inclined surface, and the second portion comprising a third inclined surface facing the bending area.
3 . The display device of claim 2 , wherein the first substrate comprises a third portion and a fourth portion spaced apart from each other with the bending area interposed therebetween, the third portion overlapping the first portion, and the fourth portion overlapping the second portion.
4 . The display device of claim 3 , wherein the fourth portion comprises a fourth inclined surface facing the bending area and aligned with the third inclined surface.
5 . The display device of claim 2 , wherein the first portion further comprises;
a first surface facing the first substrate; and
a second surface opposite to the first surface, and
wherein a first inclined angle formed by the first surface and the first inclined surface is an acute angle.
6 . The display device of claim 5 , wherein the first inclined angle is in a range of 60° to 90°.
7 . The display device of claim 5 , wherein the second surface comprises a heat-affected zone recessed vertically with respect to the second surface.
8 . The display device of claim 5 , wherein the second surface comprises a heat-affected zone protruding vertically with respect to the second surface.
9 . The display device of claim 8 , wherein a width of the heat-affected zone in a direction parallel to the first substrate is in a range of 10 μm to 100 μm.
10 . The display device of claim 1 , wherein the first bending-protection layer has a thickness in a range of 50 μm to 200 μm.
11 . The display device of claim 10 , further comprising a signal line for transmitting an electrical signal to the light-emitting element, not overlapping with the second bending-protection layer, and overlapping the first bending-protection layer.
12 . The display device of claim 1 , further comprising a via layer and a pixel definition layer between the first substrate and the second bending-protection layer, and comprising inclined surfaces facing the bending area aligned with the first inclined surface and the second inclined surface.
