To normally display an image and prevent open circuiting of drive circuits by optimizing power supplying sequences upon turn-on and turn-off of a back light of a plasma addressed display panel, a plasma addressed display panel 1 having a laminated structure of a liquid crystal cell and a plasma cell is provided, wherein the liquid crystal cell includes signal electrodes 4 arranged in columns and the plasma cell includes discharge channels 4 arranged in rows. Upon turn-off of the power switches, the supply of power to the plasma drive circuit 2 is stopped after the supply of power to the liquid crystal drive circuit 2 is stopped. Moreover, the supply of power to the drive circuits 2, 3 is stopped after a back light 8 is turned off. Upon turn-on of the power switches, the supply of power to the plasma drive circuit 2 and the liquid crystal drive circuit 3 is started after the supply of power to a control circuit 7 is started to enable the control circuit 7. Moreover, the back light 8 is turned on after the supply of power to both the drive circuits 2, 3 is started to enable the operation of both the drive circuits 2 and 3.
