DISPLAY DEVICE
摘要:
A display device which enhances time-wise likelihood for a leak current from a floating memory node by increasing the number of writing of a voltage to a floating memory node is provided. In the display device, a vertical driver circuit includes a shift register circuit and a common electrode driver circuit. The shift register circuit is constituted of a plurality of basic circuits which outputs common electrode driving pulses based on a transfer clock inputted from the outside. The common electrode driver circuit is constituted of a plurality of common basic circuits to which the respective common electrode driving pulses outputted from the respective basic circuits of the shift register circuit and the transfer clock are inputted. Each common basic circuit includes: a circuit A which fetches an AC signal based on the common electrode driving pulse; a circuit B which outputs, based on the AC signal fetched by the circuit A, a first common voltage or a second common voltage which differs from the first common voltage in voltage level to the common electrodes corresponding to the AC signal; and a circuit C which holds a state of the circuit B based on the transfer clock.
