<P>PROBLEM TO BE SOLVED: To provide a display device of an active matrix system in which organic electroluminescence (EL) elements are stacked for stably displaying an image without spoiling reliability of transistors, and which is suitable for a small display device by making a frame area well balanced, and by enabling efficient layout. <P>SOLUTION: The display device includes first display elements, second display elements, pixels, display areas, first pixel circuits, second pixel circuits, and control circuits. A high level signal voltage of a control signal supplied for the first pixel circuit is different from that of the control signal supplied for the second pixel circuit, and a low level signal voltage of the control signal supplied for the first pixel circuit is different from that of the control signal supplied for the second pixel circuit. <P>COPYRIGHT: (C)2011,JPO&INPIT |
