Abstract
An organic electroluminescent display device includes an array element layer formed on a substrate, the array element layer including a switching element, a driving element, a first electrode, an organic luminescent layer, and a second electrode, and a ground line formed on the substrate, the ground line directly contacting the second electrode.
Claims7
A method of fabricating an organic electroluminescent device, comprising:
- forming an array element layer on a substrate, the array element layer including a switching element, a driving element, a first electrode, an organic luminescent layer, and a second electrode;
- forming a ground line at a periphery of the substrate;
- forming a planarization layer on the ground line;
- exposing a portion of the ground line by forming a ground contact hole through the planarization layer;
- forming an interposition layer on the portion of the ground line;
- and
- forming the second electrode on the interposition layer and planarization layer, the second electrode electrically connected to the ground line through the interposition layer, wherein the interposition layer is for reducing a contact resistance between the ground line and the second electrode.
