Abstract
A display device includes a light-emitting device that may be disposed on an upper planarization layer of a pixel area. A bank insulating layer defining an emission area may be disposed on the upper planarization layer. The upper planarization may include a protruding portion overlapping with the emission area. An edge of the protruding portion may be a curved surface having a constant curvature. The light-emitting device may include a first electrode, a light-emitting layer and a second electrode, which are sequentially stacked on the emission area. The protruding portion may be covered by the first electrode. Thus, in the display device, a decrease in luminance according to a viewing angle may be reduced.
Claims15
A display device comprising:
- an upper planarization layer disposed on a device substrate and including a protruding portion in a pixel area;
- a first electrode disposed on the upper planarization layer and covering the protruding portion;
- a bank insulating layer disposed on the upper planarization layer and including an opening exposing a portion of the first electrode;
- a light-emitting layer disposed on the portion of the first electrode exposed by the opening of the bank insulating layer;
- and
- a second electrode disposed on the light-emitting layer and extending on the bank insulating layer,
- wherein an edge of the protruding portion has a curved surface with a constant curvature, and
- wherein the first electrode includes a curved region overlapping with the edge of the protruding portion.
A display device comprising:
- a bank insulating layer disposed on a pixel area of a device substrate, the bank insulating layer defining an emission area;
- an upper planarization layer disposed between the device substrate and the bank insulating layer, the upper planarization layer including a protruding portion overlapping with the emission area;
- and
- a light-emitting device disposed on the upper planarization layer of the emission area, the light-emitting device having a stacked structure of a first electrode, a light-emitting layer and a second electrode,
- wherein the first electrode extends between the upper planarization layer and the bank insulating layer along a surface of the protruding portion opposite to the device substrate, and
- wherein an edge of the protruding portion has a convex shape.
