ABSTRACT:
Disclosed are an organic EL(electroluminescence) display panel and a fabrication method thereof. The auxiliary electrode is formed to alternate but be overlapped with the pattern of the first electrode with a predetermined area so as to increase the pixel area as much as the overlapped area. Therefore, the present invention improves an opening ratio of the organic EL device. And, the present invention requires no additional step of forming an insulating layer for increasing an opening ratio, thereby saving a product cost for the fabrication of the organic EL device as well as being advantageous in fabrication efficiency. The present invention includes a transparent substrate, a first electrode formed on the transparent substrate, an auxiliary electrode overlapped with the first electrode in part so as to be connected to the first electrode, an organic light-emitting layer formed on the first electrode at the pixel, and a second electrode formed on the organic light-emitting layer so as to cross with the first electrode.
