One selection period S and display cycles Td of a number corresponding to
a maximum gradation level are allotted in one field, and the display
cycle Td is composed of an unselection period U and a reset period R to
perform the following control. A row electrode-driving circuit is used to
output a selection pulse Ps during the selection period S, output an
unselection signal Su during the unselection period U in the display
cycle Td, and output a reset pulse Pr during the reset period R. A column
electrode-driving circuit is used to output an ON signal during a light
emission maintenance period, and output an OFF signal at least at an end
timing of the light emission maintenance period, of the period other than
the light emission maintenance period. Accordingly, it is possible to
effectively reduce the electric power consumption, and it is possible to
achieve the high brightness.
