    摘要: An inexpensive organic electroluminescent display device is realized by using a data driver IC for liquid crystal that is used in a liquid crystal display device, as a driver of the organic electroluminescent display device. In an active-matrix organic electroluminescent display device that has a pixel circuit capable of controlling light emitting luminance per time in accordance with magnitude of a grey scale voltage, a control signal is supplied from a timing control IC to the data driver so that the polarity is reversed twice consecutively, or a control signal is supplied from the timing control IC to the data driver so that a mode of not reversing the polarity is selected. This control signal need not necessarily be provided in the timing control IC and may be formed in a circuit on a substrate that is not an IC.
