Abstract: A precharge circuit is composed of (a) a reference signal input section, to which at least one precharge reference potential is inputted, (b) a control signal input section, to which at least one control signal is inputted, (c) a plurality of signal delay sections for sequentially delaying an output of the control signal input section, and (d) a reference signal switching section for switching, in accordance with outputs of the signal delay sections, between a state of outputting the precharge reference potential of the reference signal input section to each of the data signal lines and a state of non-outputting the same thereto. With this arrangement, the precharge control signal is sequentially delayed within the precharge circuit by the delay circuits composed of inverter circuits or the like, so that timings at which the precharge reference potential is written in the data signal lines are dispersed.

Abstract: A digital-to-analog conversion circuit of charge distribution type includes a plurality of capacitors having respective capacitances that increase in a sequential order, one end of the capacitors being commonly connected electrically. The circuit also includes a plurality of analog switches each for electrically connecting a reference potential corresponding to a digital signal inputted from outside to the other end of the corresponding capacitor. These analog switches have respective driving capacities that increase in a sequential order.
