<p>A discharge lamp lighting device includes a voltage pulse applying section adapted to apply a voltage pulse for causing dielectric breakdown between first and second electrodes of a discharge lamp, an alternating-current voltage applying section adapted to apply an alternating-current voltage to the discharge lamp, the alternating-current voltage including a first polarity period in which the first electrode acts as an anode and a second polarity period in which the second electrode acts as the anode, and a control section. The control section controls the voltage pulse applying section to cause the dielectric breakdown, and thereafter controls the alternating-current voltage applying section to apply the alternating-current voltage having the first polarity period longer than the second polarity period to the discharge lamp, and thereafter to apply the alternating-current voltage having the second polarity period longer than the first polarity period to the discharge lamp.</p> |
