An organic light emitting display device is provided to prevent occurrence of a current variation among pixels with the same color by including: a display panel which has first pixels to display first color, second pixels to display second color and third pixels to display third color; a data driving circuit to generate a data voltage; a demux switching circuit to supply data voltage through time division, which is inputted from one output channel of the data driving circuit to N number of data lines formed on the display panel by including first to N (N is a positive integer, greater or equal to 2) number of demuxing switches connected to each output channel of the data driving circuit; and a control signal generation unit to generate first to N number of demuxing control signals to control operation of each of the first to N number of demuxing switches, wherein the first to N number of demuxing control signals successively rise to on-level within a programming period in which a first scan signal stays at on-level to write the data voltage with pixels, and successively fall to an off-level. |
