Abstract
A light emitting display device includes a substrate and a switching element disposed on the substrate. A pixel electrode is disposed on the substrate and is connected to the switching element. A pixel defining layer is disposed on the pixel electrode. The pixel defining layer defines a pixel area of the substrate. A light emitting layer is disposed on the pixel electrode. A common electrode is disposed on the light emitting layer and the pixel defining layer. A sealing layer is disposed on the common electrode. A first light blocking layer is disposed between the pixel defining layer and the sealing layer.
Claims23
A display device comprising:
- a substrate;
- a switching element disposed on the substrate;
- a pixel electrode disposed on the substrate and connected to the switching element;
- a pixel defining layer disposed on the pixel electrode, the pixel defining layer defining a pixel area of the substrate;
- a light emitting layer disposed on the pixel electrode;
- a common electrode disposed on the light emitting layer and the pixel defining layer;
- a sealing layer disposed on the common electrode;
- and
- a first light blocking layer disposed between the pixel defining layer and the sealing layer.
A display device, comprising:
- a substrate;
- a driving circuit disposed on the substrate;
- a pixel defining layer disposed on the driving circuit, the pixel defining layer having a first opening at least partially overlapping a pixel area of the substrate;
- a light emitting element disposed over the driving circuit within the pixel area;
- a first light blocking layer disposed over the pixel defining layer, the first light blocking layer having a second opening at least partially overlapping the pixel area of the substrate;
- a sealing layer disposed over the first light blocking layer and the light emitting element;
- and
- a second light blocking layer disposed over the sealing layer, the second light blocking layer having a third opening at least partially overlapping the pixel area of the substrate.
