An organic electroluminescent device and a driving method thereof are provided to restrict an image from stopping even if the changed luminance control data is input, by separating RGB(Red,Green,Blue) data input line and luminance control data input line. An organic electroluminescent device includes a panel(200) having pixels(E11~E44) formed in each emission region where data lines(D1~D4) and scan lines(S1~S4) cross each other, and a data driving unit(230) driving the pixels according to RGB data and luminance control data input from the outside. The data driving unit comprises an RGB data recognition unit(232) to which the RGB data is input, and a current generating unit(234) for receiving the luminance control data and applying data current corresponding to the RGB data detected in the RGB data recognition unit, to the data lines.
