To control flickering in light emission of a phosphor and improve brightness to enhance light emitting efficiency.
In a method of driving a cold-cathode fluorescent lamp, a positively polarized voltage (first voltage) is applied to an anode 13 to discharge electrons from each of a lot of electron discharging points on a cathode 14 toward the anode 13 through electric field concentration and these discharged electrons are bombarded with a phosphor 12 on the anode 13 to excite the phosphor 12 to emit light. In this method, flickering in light emission of the phosphor 12 is controlled by repeating a first step of applying the first voltage to the anode 13 and a second step of purging electrons charged by this application of the first voltage from the phosphor 12 by applying a positive voltage (second voltage) to the cathode 14.
