<p>The present invention relates to an organic electroluminescent display device which is driven in a simultaneous light emitting manner. The organic electroluminescent display device of the present invention comprises: a scan driving unit to simultaneously supply scan signals to scan lines during a first period of one frame, and to sequentially supply scan signals to the scan lines for a second period; a data driving unit to supply data signals to data lines to be synchronized with the scan signals that are sequentially supplied during the second period; pixels which are located to be connected to the scan lines and the data lines; a first power driving unit to supply, to the pixels, first power that is changed to a low level and a high level during one frame period; and a second power driving unit to supply, to the pixels, second power that is changed to a low level and a high level during one frame period, wherein the first period is divided into an initialization period, a threshold voltage compensation period, and a stabilization period, and supplied to the data lines are a voltage of first initialization power during a portion of the initialization period, a voltage of reference power which is set as a voltage value higher than a first initialization voltage during the threshold voltage compensation period, and a voltage of second initialization power which is set as a voltage value lower than the reference voltage during the stabilization period.</p> |
