ABSTRACT:
A plasma display panel includes front and rear substrates; anodes in a stripe pattern on a facing surface of the front substrate; a lower electrode coating the entire facing surface of the rear substrate; a dielectric layer coating the lower electrode; an upper electrode coating the dielectric layer in a pattern; and a lattice of partition walls between the upper electrode and the front substrate. The portions of the dielectric layer between the partition walls and not coated with the upper electrode form respective pixels. Sputtering is minimized and there is less damage to the electrodes by the gas, thus extending the length of use of the product. The ferroelectric material of the lower electrode has excellent resistance with respect to the discharge gas and the discharge can be initiated with a low initial discharge starting voltage since the ferroelectric cathode provides enough electrons for the discharge.
