Abstract
Embodiments of an organic electroluminescence display device and methods of fabricating such devices are disclosed. One embodiment of an organic electroluminescence display device comprises a thin film transistor and wirings disposed on a substrate, wherein the substrate has an emitting region and non-emitting region. The display device further comprises a first insulating layer disposed on the substrate in the emitting region and the non-emitting region, a pixel electrode disposed on the first insulating layer, a second insulating layer disposed on the emitting region to partially expose the pixel electrode, a light-emitting layer disposed on the pixel electrode, and an encapsulation member disposed on the second insulating layer on the non-emitting region.

An organic electroluminescence display device, comprising:
- a thin film transistor and wirings disposed on a substrate having an emitting region and non-emitting region;
- a first insulating layer disposed on the emitting region and the non-emitting region of the substrate;
- a pixel electrode disposed on the first insulating layer;
- a second insulating layer disposed in the non-emitting region and in the emitting region with an opening to partially expose the pixel electrode and formed of an inorganic insulating material;
- a light-emitting layer disposed on the pixel electrode;
- and
- an encapsulation member disposed on the second insulating layer in the non-emitting region.
A method of fabricating an organic electroluminescence display device, comprising:
- forming a thin film transistor and wirings on a substrate having an emitting region and non-emitting region;
- forming an insulating layer on the substrate to form a first insulating layer on the emitting region and the non-emitting region of the substrate;
- forming a via in the first insulating layer in the emitting region;
- forming a pixel electrode connected to a lower thin film transistor through the via;
- forming an inorganic insulating layer over the substrate;
- pattering the inorganic insulating layer to expose the pixel electrode;
- forming a light-emitting layer on the exposed pixel electrode in the emitting region;
- and
- encapsulating the substrate and layers formed thereon.
