Abstract
There is provided a display device in which disadvantageous effects due to unnecessary operations of an image lag alleviating function are minimized. In a display device of active matrix type, for each of the pixels arranged in a matrix, a current-driven emissive element is provided, and the current of the emissive element is controlled using a drive TFT so as to perform display. While a black display period during which an opposite bias voltage is applied between the gate electrode and the source electrode of the drive TFT is inserted in order to alleviate image lag, this insertion is performed only when a predetermined condition is satisfied, and is performed for a certain duration according to a command by a microcomputer ().
