摘要： 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.

摘要： In a display device which includes a driver circuit having a shift register circuit, the shift register circuit is constituted of basic circuits in plural stages. Each basic circuit is constituted of a circuit A, a circuit B and a circuit C. The circuit A fetches a first drive clock (or a second drive clock) inputted from the outside when transfer data is inputted to the circuit A from a circuit of preceding stage, outputs the transfer data as a shift output of own stage, and transfers the transfer data to the circuit B. The circuit B transfers the transfer data to the circuit A of the basic circuit of the succeeding stage, and resets the circuit C. The circuit C resets the circuit A and the circuit B in synchronism with the first drive clock (or the second drive clock) generated at next timing or succeeding timing of the first drive clock.
