    摘要： The present invention relates to a plasma display apparatus. The plasma display apparatus includes a first layer and a second layer over an upper substrate of a plasma display panel. The first layer emits light having a peak at a first wavelength region with light emitted from a discharge space. The second layer emits light having a peak at a second wavelength region lower than the first wavelength region with light emitted from a discharge space. The first layer and the second layer are disposed over a dielectric layer of the upper substrate. The plurality of scan electrodes are divided into first and second groups and then supplied with scan signals, and scan bias voltages supplied to the first and second groups in at least one period of an address period are different from each other. Accordingly, the occurrence of address erroneous discharge due to the loss of wall charges can be reduced and the discharge efficiency can be enhanced. Further, consumption power for panel driving can be saved and driving margin of a panel can be secured sufficiently.
