Abstract

A plasma display device includes a front substrate, first and second electrodes in parallel on an inner surface of the front substrate, a first dielectric layer on the inner surface of the front substrate covering the first electrode, a rear substrate facing the front substrate, a third electrode on an inner surface of the rear substrate crossing the first and second electrodes perpendicularly, a second dielectric layer on the inner surface of the rear substrate covering the third electrode, partitions forming discharge spaces opposite the dielectric layer of the rear substrate, and a phosphor coating side surfaces of respective partitions and producing red, green, or blue light. In the plasma display device, the width of the first or second electrodes at the discharge space coated with the phosphor emitting blue light, extending toward a region where light is not emitted, is larger than the widths of each of the first and second electrodes at discharge spaces coated with the phosphors producing red and green light. Thus, white balance can be easily represented and the brightness of the device is improved.
