A discharge is produced in discharge cells only in an address erasing process for one subfield selected from a plurality of subfields constituting a unit display period, so that the states of the discharge cells are changed to a non-light emitting state.

In this case, in either of the address writing process and the address erasing process, the discharge is produced between one of the row electrode pairs and the column electrodes by supplying a voltage for charging the column electrodes to a negative polarity between the one of the row electrode pairs and the column electrodes.

The LCD driving voltage generating circuit comprises a DC-DC converter for boosting an input voltage in response to a clock signal and for outputting the boosted voltage as a first driving voltage; a voltage controlled oscillator for generating the clock signal at a frequency that changes in response to the level of a control voltage; and a control voltage generator for generating the control voltage in response to the difference between a reference voltage and a feedback voltage derived from the first driving voltage. In this manner, as the feedback voltage becomes lower than a reference voltage, the frequency of the clock signal input into a DC-DC converter increases.
