PURPOSE: An organic electroluminescent display device is provided to resolve voltage enhancement problems with respect to a power line by minimizing resistance value difference between a main power line and a sub power line. CONSTITUTION: An organic electroluminescent display device comprises a display panel (100), a plurality of main power lines (410), a sub power line (420), and a sub metal layer (430). The display panel comprises a plurality of scanning lines (310) and a plurality of pixels. The scanning lines comprise a plurality of data lines (210) arranged into a first direction and a plurality of scanning lines arranged into a second direction. A plurality of pixels is arranged in the cross-domain of the scanning lines and data lines. The main power lines and the sub power lines are alternately arranged with respect to each other in order to deliver a first power source to each pixel. The resistance value of the sub metal layers is lower than the same of the sub power. The sub metal layers are overlapped on the sub powers which are arranged between adjacent pixels. Electrode layers are connected electrically with the sub power lines. |
