ABSTRACT:
To provide a self-luminous device capable of clear, multi-gray scale, color display and an electric machine provided with the same. Gray scale display is attained by a time division driving method in which an EL element (109) provided in a pixel (104) is controlled to emit light or not to emit light by means of time, thereby avoiding being affected by fluctuation in characteristic in current controlling TFTs (108).
