Plasma display panel

A flat panel display apparatus comprises plasma discharge cells, which formed between a first base plate ( 2 a) and a second base plate ( 1 a). The first base plate ( 2 a) has pairs of sustain electrodes ( 2 b, 2 c), and a second base plate ( 1 a) has data electrodes ( 1 b). Between said electrodes ( 2 b, 2 c, 1 b) discharge volumes are formed. The device further has a drive circuit which comprises a circuit for providing data to the discharge cells. The display device comprises a conductive layer ( 51, 72, 91, 101 ) on the first ( 2 a) or second substrate ( 1 a) for both of a pair of sustain electrodes ( 2 b, 2 c). Said conductive layer ( 51, 72, 91, 101 ) extends outside the discharge volume ( 4 ) and forms an internal capacitance (Cpar) in the display device which capacitance is in parallel to the capacitance formed in operation by the pair of sustain electrodes and the discharge.
