Abstract
A dual panel-type organic electroluminescent display device includes a first substrate on which gate and data lines cross each other to define sub-pixels. Array elements are disposed at the sub-pixels on the first substrate. A first electrode is disposed on substantially the entire surface of a second substrate opposing the first substrate. An insulating pattern is disposed on the first electrode, an organic electroluminescent layer is disposed on the first electrode, and a second electrode is disposed on the organic electroluminescent layer at each sub-pixel. A connection pattern connects the array element and the second electrode at each sub-pixel. The connection pattern contacts the second electrode under the insulating pattern.
Claims9
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 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 at the at least one of the sub-pixels;
- forming a connection pattern 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.
