Abstract
An organic light emitting display having first pixel power source lines receiving a pixel driving voltage from first power supply sources and second pixel power source lines arranged between the first pixel power source lines and receiving a pixel driving voltage from second power supply sources, the light emitting diode of each of a plurality of pixels included in an image display unit is divided into two, and the divided light emitting diodes are coupled to the different pixel power source lines so that brightness non-uniformity of the image display unit caused by the IR drops of the pixel power source lines is reduced or prevented.
