Abstract

PURPOSE: To considerably shorten the time lag of starting, by providing DC starting electrode as well as AC starting discharge cell.
CONSTITUTION: DC starting electrodes 16 are arranged on both sides of starting electrode 15, and the rectifying circuit 3 is connected to DC starting electrode 16. DC voltage rectified by rectifying circuit 3 and applied on electrode 16 is combined with the sustain voltage applied on X-axis electrode 12 of facing substrate 11 and lights the starting discharge cell located at the cross point between the electrode 16 and the facing X electrode 12. The initial charge caused by said discharge lights immediately the starting discharge cell related to conventional starting electrode 15. Since the electrode for determinig the starting cell is coated with insulation layer, the cancelling voltage due to wall charge occurs thereby the starting discharge cell lights only one time immediately after throw-in of power source due to said DC starting electrode and causes no obstruction for the indication.
