摘要： A light emitting display includes a substrate, a pixel area, a first power source line to supply a first power signal to each pixel on a first side of the pixel area, a second power source line to supply the first power signal to each pixel on a second side of the pixel area, and an impedance compensator for compensating a difference in a voltage drop between the first power source line and the second power source line. A voltage drop caused by line resistance that depends on the length of the first and second power source line that supply the first power signal to a lower and upper side of a pixel area, respectively, is equalized, thereby minimizing the voltage drop of the first power signal supplied to all pixels, and minimizing non-uniformity of brightness due to the voltage drop differences at each pixel.
