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.

Description

technical field [0001] The present invention relates to an organic electroluminescence display and a manufacturing method thereof, and more particularly, the organic electroluminescence display includes grooves formed on the insulating layer under the encapsulation to increase the gap between the insulating layer and the sealant Adhesion. Background technique [0002] A flat panel display including an organic electroluminescent display has a fast response speed of less than 1 ms and low power consumption. Furthermore, since organic electroluminescent displays are self-emitting devices, viewing angle issues are minimal. Also, the organic electroluminescence display can efficiently display high-quality video images. With regard to manufacturing advantages, organic electroluminescent displays can be manufactured at low temperatures, and their manufacturing process can be simplified by using current semiconductor production technologies. Therefore, organic electroluminescent ...
