Abstract
An organic light emitting display device capable of displaying an image of uniform brightness. A scan driver drives scan lines and light emitting control lines that are formed parallel to each other. A data driver drives data lines formed at a direction intersecting the scan lines and the light emitting control lines, and pixels are disposed to be coupled with the scan lines, the light emitting control lines, and the data lines. An auxiliary line is formed parallel to the data lines. One side of the auxiliary line is coupled with a reference power supply and another side of the auxiliary line is coupled with a current source. Connectors are disposed at crossing areas of the auxiliary line and the scan lines. A voltage transfer unit is coupled with the connectors and transfers a voltage supplied to the connectors to the data driver.
