An organic electroluminescent display and driving method thereof. The organic electroluminescent display includes a demultiplexer for outputting signals provided by a data driver to a plurality of data lines according to on/off operation of analog switches. The driving method divides a frame into two parts, and drives them. Data signals are applied to pixels which are not adjacent among the pixels of each row during the former ½ frame, and the data signals are applied to the pixels to which no data signal has been applied in the former ½ frame during the latter ½ frame.
