ABSTRACT:
The present invention provides a display device including a scanning driving circuit which exhibits the high degree of freedom in designing of waveforms of scanning signals while ensuring the reduction of power consumption. A shift register served for a scanning driving circuit is driven at a voltage lower than a voltage amplitude of scanning signals. Booster circuits are provided corresponding to respective stages of the shift register. To each booster circuit, a common scanning signal which is in common with other booster circuits is inputted as a signal separate from a shift register output. The scanning signal is selected from the common scanning signal during a period in which the scanning signal is selected in response to the shift register output and the selected scanning signal is outputted to respective gate lines.
