<P>PROBLEM TO BE SOLVED: To prevent through current while suppressing the circuit area. <P>SOLUTION: This driving device includes a shift register that stores a value indicated by an input signal, sequentially shifts to adjacent bits, and outputs the values of a plurality of stored bits, a logical sum circuit for determining the logical sum of a plurality of data signals showing the values of the plurality of non-adjacent bits of the shift register, respectively, and outputting it, a delay circuit for delaying and outputting an output of the logical sum circuit, a plurality of timing generating circuits that correspond to the plurality of data signals and generate a first control signal including a first pulse and a second control signal including a second pulse according to the corresponding data signal and the output of the delay circuit, and a plurality of output circuits that correspond to the plurality of timing generating circuits and output the voltage of a first power supply according to the first control signal of the corresponding circuit and the voltage of a second power supply according to the second control signal of the corresponding circuit. The period of the second pulse includes the period of the first pulse. <P>COPYRIGHT: (C)2010,JPO&INPIT |
