An organic light emitting display device includes: a scan driver configured to sequentially supply a scan signal to scan lines, and supply an emission control signal to emission control lines; a data driver configured to supply a data signal to data lines; a pixel unit (pixel region) including pixels connected with the scan lines, the emission control lines, and the data lines and receiving a first power source which is a high potential pixel power source, a second power source which is a low potential pixel power source, and a third power source which is an initialization power source; and a wiring connecting an anode electrode of an organic light emitting diode of a first pixel in a first horizontal line and a first electrode of a transistor connected with the third power source of a second pixel in a second horizontal line while being adjacent to the first pixel.
