Abstract

A plasma display panel capable of reducing power consumption by lowering address discharge voltage and electrostatic capacitance among electrodes. The plasma display panel includes a front and a rear substrate facing each other; barrier ribs which are located on the rear substrate to define discharge cells; phosphor layers formed on the inner sides of the discharge cells; an intermediate substrate located over the barrier ribs; spacers located between the front and intermediate substrates; address electrodes which are formed on the intermediate substrate and sustain and scan electrodes which are formed on the front substrate along a direction crossing the direction of the address electrodes. A space between the front and intermediate substrates is under vacuum or filled with a fluid having a low permittivity in order to keep the address discharge voltage between the electrodes low.

Claims

a first substrate;

a second substrate facing the first substrate;

barrier ribs located on the first substrate to define discharge cells;

phosphor layers formed on inner surfaces of the discharge cells;

a third substrate located between the first substrate and the second substrate and over the barrier ribs;

spacers located between the second substrate and the third substrate;

address electrodes formed on the third substrate along a first direction and corresponding to the discharge cells; and

first electrodes and second electrodes formed on the second substrate along a second direction crossing the first direction and corresponding to the discharge cells.

2. The plasma display panel of claim 1, wherein the spacers are located along the second direction corresponding to a boundary between the discharge cells neighboring in the first direction.

3. The plasma display panel of claim 1, wherein a substantial vacuum is formed between the second substrate and the third substrate.

4. The plasma display panel of claim 1, wherein a fluid is filled between the second substrate and the third substrate.

5. The plasma display panel of claim 4, wherein the fluid is an inert gas.

8. The plasma display panel of claim 1, wherein the spacers are formed from glass beads.

9. The plasma display panel of claim 1, wherein the spacers are etched from the third substrate.

10. The plasma display panel of claim 1, wherein the third substrate is a transparent glass.

11. The plasma display panel of claim 1, wherein the address electrodes are formed on one surface of the third substrate facing the first substrate.

12. The plasma display panel of claim 11, wherein each address electrode includes:

an extended portion extending in the first direction corresponding to a boundary position of the discharge cells neighboring in the second direction; and

a protruded portion protruding in the second direction towards the inner part of the discharge cells.

13. The plasma display panel of claim 12, wherein the extended portion is metal, and the protruded portion is transparent ITO.

14. The plasma display panel of claim 11, wherein a dielectric layer is formed over the address electrodes.

16. The plasma display panel of claim 1, wherein the first electrode and the second electrode each include:

transparent electrodes corresponding to the discharge cells; and

bus electrodes connecting the transparent electrodes in the second direction.

17. The plasma display panel of claim 1, wherein the barrier ribs include first barrier members formed on the first substrate and extending in the first direction.

18. The plasma display panel of claim 17, wherein the barrier ribs further include second barrier members formed between the first barrier members and extending in the second direction.
