Abstract:
1. A method for manufacturing a dual panel-type organic electroluminescent display device, the method comprising: forming gate and data lines crossing each other on a first substrate to define sub-pixels; forming an array element at at least one of the sub-pixels on the first substrate, the array element including a switching thin film transistor and a driving thin film transistor; forming a first electrode on substantially an entire surface of a second substrate; forming an insulating pattern on the first electrode at the at least one of the sub-pixels; forming organic electroluminescent layers on the first electrode within the at least one of the sub-pixels; forming a second electrode on the organic electroluminescent layer and the insulating pattern at the at least one of the sub-pixels; forming a connection pattern on the second electrode and connected to the driving thin film transistor at the at least one of the sub-pixels; and attaching the first and second substrates such that the connection pattern contacts the second electrode on the insulating pattern, wherein the connection pattern overlaps the insulating pattern except the organic electroluminescent layer wherein the organic electroluminescent layer and the insulating pattern are entirely disposed at the same layer and have substantially the same thickness to form a flat surface.
