Abstract: An intermediate electrode is formed in a space between an X display electrode and a Y display electrode parallel thereto. A negative voltage is applied to the Y display electrode to use the Y display electrode as a cathode. A charge is stored between the Y display electrode and an intermediate electrode to create an electric field. Upon the increase of the intensity of the electric field to a sufficiently high level, an instant discharge occurs between the Y display electrode and the X display electrode and intense ultraviolet rays are produced. The fluorescent layer excited by the ultraviolet rays emits visible light. Only a narrow pulse current flows through the X display electrode and the Y display electrode, so that power consumption can be suppressed at high emission efficiency.

Taking a 3-bit 8-gradation display as an example, a first H period (one horizontal scan period) of each subfield is divided into 3 regions (first region, second region, and third region in the order of time), and, in each of the lines, an address period (address pulse PA and scan pulse PAY) of the subfield SF1 is set in the first region, an address period of subfield SF2 is set in the second region, and an address period of the subfield SF3 is set in the third region. The regions other than those in which the address period is set are used as the sustain period, and a time length of each sustain pulse Ps is set to ? of the length of the H period. A reset period achieved by a reset pulse PR and a priming period achieved by a priming pulse PP are set in the region where the address period is set.
