Abstract
The present invention relates to an AC drive surface discharge type plasma display panel having an isosceles delta array type pixel. The background art has a problem of being apt to cause a wrong writing discharge and having a narrow writing voltage margin. Then, in the present invention, transparent electrodes for X electrode (T, T) in first and second pair subpixel regions (PSPR, PSPR) of an isosceles delta array type pixel (P) are provided at portions farther away from a first write electrode (Wj(B)) in an isolated subpixel region (ISPR). Specifically, a central axis of the third transparent electrode (T) along a vertical direction (v) is positioned closer to an extending portion (WAE) of a second write electrode (Wj(A)) from a vertical direction central axis of the first pair subpixel region (PSPR). Similarly, a vertical direction central axis of the fourth transparent electrode (T) is positioned closer to an extending portion (WCE) of a third write electrode (Wj(C)) from a vertical direction central axis of the second pair subpixel region (PSPR). The present invention is mainly used for a display device such as a plasma television.
