摘要： An inverter includes an input inverter having a high-resistance load and a first transistor and an output buffer including second and third transistors coupled in series. A power supply voltage is provided to satisfy an inequality VDD1>VDD2+Vth where VDD1 is the power supply voltage of the input inverter, VDD2 is the power supply voltage of the output buffer, and Vth is the threshold voltage of the transistors. Use of the high-resistance load allows an output waveform to rise and fall quickly, as well as reduces current consumption.

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.

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.
