ORGANIC ELECTROLUMINESCENCE EMITTING DISPLAY DEVICE

摘要

PURPOSE: An organic electroluminescent display device is provided to improve the reliability of a device by preventing non-uniformity of brightness due to a voltage drop phenomenon. CONSTITUTION: A display panel(110) is defined with a display region and a non-display region. A sub pixel(115) is defined by the vertical intersection of a gate line(Sn) and a data line(Dm). The sub pixel includes an organic light emitting diode, a driving switching device, and a switching device for a power supply. The organic light emitting diode displays an image with a driving current. A power supply pad unit(130) is arranged in the non-display region of the display panel and supplies a power voltage to the sub pixel.
