PROBLEM TO BE SOLVED: To provide a display device used mainly for air conditioning of an automobile or operation of acoustic equipment, which can perform easy-to-view display by simple structure. SOLUTION: In the display device, a first delay means 11 is provided between a first voltage supply means 6 connected to an anode 3 of a fluorescent display tube 1 and a third voltage supply means 8 connected to a logic 5 to delay the application of voltage to the anode 3 or filament 4. The voltage is regularly applied to the logic 5 first in power supply, whereby the segment 2 is prevented from flashing without being controlled by the logic 5. Accordingly, the display device can perform easy-to-view display by simple structure. COPYRIGHT: (C)2009,JPO&INPIT
