ABSTRACT OF THE DISCLOSURE A method of driving a thin film EL display device is characterized by that, when the Y side scanning electrodes are clamped selectively and sequentially to the reference voltage and the display voltage applied selectively from the X side data electrodes, a non-display voltage which is lower than the display threshold voltage is applied to the non-selected data electrodes and the non-selected scanning electrodes are floated. This new driving method is effective for reducing the driving power and widening the operating voltage range.
