Display device
A display device includes pixels including a light emitting area and a non-light emitting area; light emitting elements disposed in the light emitting area; and a bank disposed in the non-light emitting area. The bank includes an opening overlapping the light emitting area in a plan view; a first area spaced apart from the opening; and a second area surrounding the opening and the first area, and a thickness of the second area is greater than a thickness of the first area.
1 . A display device comprising:
a display panel comprising pixels and having a light emitting area and a non-light emitting area;
light emitting elements disposed in the light emitting area; and
a bank disposed in the non-light emitting area and on a substrate,
wherein the bank includes:
an opening overlapping the light emitting area in a plan view;
a first area spaced apart from the opening; and
a second area surrounding the opening and the first area,
wherein a thickness of the second area is greater than a thickness of the first area, and
wherein the first area and the second area are entirely formed of a same material.
2 . The display device of claim 1 , further comprising:
a first electrode and a second electrode spaced apart from each other,
wherein the light emitting elements are disposed between the first electrode and the second electrode.
3 . The display device of claim 2 , further comprising:
a first connection electrode disposed on a first end portion of the light emitting elements and on the first electrode; and
a second connection electrode disposed on a second end portion of the light emitting elements and on the second electrode.
4 . The display device of claim 1 , wherein the first area includes:
a first sub-area spaced apart from the opening in a first direction; and
a second sub-area spaced apart from the opening in a second direction intersecting the first direction.
5 . The display device of claim 4 , wherein a width in the second direction of the first sub-area is substantially equal to a width in the second direction of the opening.
6 . The display device of claim 4 , wherein a width in the first direction of the second sub-area is substantially equal to a width in the first direction of the opening.
7 . The display device of claim 1 , wherein
the first area includes a first sub-area and a second sub-area spaced apart from each other, and
the opening, the first sub-area, and the second sub-area are arranged in a second direction.
8 . The display device of claim 7 , wherein a width in a first direction of the first sub-area and/or a width in the first direction of the second sub-area are equal to a width in the first direction of the opening, the first direction intersecting the second direction.
9 . The display device of claim 1 , further comprising:
a color conversion layer disposed in the opening.
10 . The display device of claim 1 , wherein a thickness of the first area is about 6 μm or more.
11 . The display device of claim 1 , wherein the bank has a reversed-tapered shape.
12 . A display device comprising:
a display panel comprising pixels and having a light emitting area and a non-light emitting area;
a bank including a first opening overlapping in a plan view the light emitting area and a second opening overlapping the non-light emitting area;
a color conversion layer disposed in the first opening;
a first optical layer disposed on the color conversion layer; and
a second optical layer disposed in the second opening.
13 . The display device of claim 12 , wherein a thickness of the bank is greater than a thickness of the second optical layer.
14 . The display device of claim 12 , wherein a thickness of the second optical layer is about 6 μm or more.
15 . The display device of claim 12 , wherein a refractive index of the first optical layer and/or a refractive index of the second optical layer are about 1.1 to about 1.3.
16 . The display device of claim 15 , wherein the first optical layer and the second optical layer include a same material.
17 . The display device of claim 12 , further comprising:
a capping layer disposed between the color conversion layer and the first optical layer.
18 . The display device of claim 12 , wherein the pixels include:
a first pixel emitting light of a first color;
a second pixel emitting light of a second color; and
a third pixel emitting light of a third color.
19 . The display device of claim 18 , wherein the color conversion layer includes:
a first color conversion layer disposed in the first pixel;
a second color conversion layer disposed in the second pixel; and
a scattering layer disposed in the third pixel.
20 . The display device of claim 19 , further comprising:
a first color filter disposed on the first color conversion layer;
a second color filter disposed on the second color conversion layer; and
a third color filter disposed on the scattering layer.
