An organic light emitting display device, wherein the device includes a scan driver for supplying a scan signal to scan lines during a frame time-divided into a plurality of subframes, a data driver coupled to output lines for supplying data signals on each of the output lines, demultiplexers coupled to the output lines for supplying the data signals to data lines, and pixels located at crossing regions of the data lines and the scan lines. Each of the demultiplexers includes a switch coupled between a corresponding one of the output lines and a first data line of the data lines, and a second data line of the data lines is directly coupled to the corresponding one of the output lines.
