Abstract:
The present invention relates to a light emitting display device, such as an organic electroluminescent device, and a method for manufacturing the same. Particularly, the present invention relates to reducing electrical resistance between the scan lines and the cathode electrode layers so that scan line signals do not degrade significantly degrade. One way to achieve this is to use materials to form the conducting layers of the scan line and the cathode electrode layers such that the conductivities of the conducting layers and the cathode electrode layer are as identical as possible. For example, if a same metal such as aluminum is used to form both the conducting layer and the cathode electrode layer, the resistance would be significantly lowered. In addition, a large contacting area may be provided.
