Abstract

A display device including a display area and a non-display area, an inorganic insulating layer disposed on a substrate, the inorganic insulating layer disposed in the display area and the non-display area, pixels disposed on the substrate and overlapping the inorganic insulating layer in a plan view, the pixels disposed in the display area, and an organic insulating layer disposed on the substrate and overlapping the inorganic insulating layer and the pixels in a plan view, the organic insulating layer disposed at least in the display area. The non-display area includes an organic layer-free area including at least one of a corner and an outer edge area of the display device. The organic insulating layer is disposed on a portion of the substrate so as to be disposed in an area except for the organic layer-free area.

Claims (40)

1 . A display device comprising:

a display area and a non-display area;

an inorganic insulating layer disposed on a substrate, the inorganic insulating layer disposed in the display area and the non-display area;

pixels disposed on the substrate and overlapping the inorganic insulating layer in a plan view, the pixels disposed in the display area;

an organic insulating layer disposed on the substrate and overlapping the inorganic insulating layer and the pixels in a plan view, the organic insulating layer disposed in the display area;

edge areas disposed in different portions of the non-display area; and

corner areas where the edge areas meet, wherein

the non-display area includes an organic layer-free area,

the organic insulating layer is disposed on the substrate so as to be disposed in an area except for the organic layer-free area,

the organic layer-free area includes the corner areas,

the edge areas include a first edge area including a pad area,

the organic layer-free a rea further includes the first edge area, and

the organic insulating layer is further disposed in a portion of remaining edge areas of the edge areas except for the first edge area.

2 . The display device according to claim 1 , wherein the organic insulating layer is disposed in a center area of each of the remaining edge areas except for ends corresponding to the corner areas in each of the remaining edge areas.

3 . The display device according to claim 2 , wherein the organic insulating layer has a width corresponding to a width of each of the remaining edge areas in the center area of each of the remaining edge areas.

4 . The display device according to claim 2 , wherein the organic insulating layer has a width less than a width of each of the remaining edge areas in the center area of each of the remaining edge areas.

5 . The display device according to claim 2 , wherein the non-display area comprises:

a first non-display area adjacent to the display area and surrounding the display area; and

a second non-display area adjacent to the first non-display area and surrounding the first non-display area.

6 . The display device according to claim 5 , wherein the organic insulating layer is disposed in the first non-display area in the center area of each of the remaining edge areas, and the second non-display area includes an outer edge area of the display device and corresponds to the organic layer-free area in a plan view.

7 . The display device according to claim 5 , wherein the non-display area further includes a third non-display area surrounding the second non-display area and including an outer edge area of the display device.

8 . The display device according to claim 7 , wherein

the organic insulating layer is disposed in the first non-display area and the third non-display area in the center area of each of the remaining edge areas, and

the second non-display area corresponds to the organic layer-free area.

9 . The display device according to claim 8 , wherein the organic insulating layer disposed in the third non-display area is separated from the organic insulating layer disposed in the display area and the first non-display area.

10 . The display device according to claim 1 , wherein each of the pixels includes a light emitting unit including at least one light emitting element.

11 . The display device according to claim 10 , wherein the organic insulating layer comprises:

a first organic insulating layer between the light emitting unit of each of the pixels and the inorganic insulating layer, the first organic insulating layer being disposed entirely in the display area; and

a second organic insulating layer disposed on the light emitting unit of each of the pixels, the second organic insulating layer being disposed entirely in the display area.

12 . The display device according to claim 11 , further comprising:

a light conversion layer between the light emitting unit of each of the pixels and the second organic insulating layer, the light conversion layer including at least one of wavelength conversion particles or light scattering particles that are disposed in an emission area of each of the pixels; and

a color filter layer including a color filter disposed on the second organic insulating layer and overlapping the light emitting unit of each of the pixels in a plan view.

13 . The display device according to claim 12 , wherein the organic insulating layer further includes a third organic insulating layer disposed on the color filter layer, the third organic insulating layer being disposed entirely in the display area.

14 . The display device according to claim 10 , wherein each of the pixels further includes a pixel circuit including a transistor electrically connected to the light emitting unit.

15 . The display device according to claim 14 , further comprising:

a circuit layer disposed with the pixel circuits of the pixels,

wherein the inorganic insulating layer includes a plurality of inorganic insulating layers disposed on the circuit layer.

16 . The display device according to claim 1 , wherein

the display area is disposed in a center area of the display device, and

the non-display area is disposed in an edge area of the display device and has a width of about 50 micrometers or less.
