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.

Surface discharge type plasma display panel having an isosceles delta array type pixel

Components of an arrangement interval in first and second directions (v, h) between first to third subpixels (C C C ) in a pixel (PX) satisfy the following expressions: pv &equals;pv &equals;pv/2; pv &equals;0; and ph &equals;ph <ph/3. Components of the arrangement interval in the first and second directions (v, h) between two pixels (PX) adjacent to each other in the second direction (h) satisfy the following expressions: pv &equals;pv/2 (&equals;p/2); pv &equals;0; and ph >ph/3. Pixels (PX) adjacent to each other in the first direction (v) have the same arrangement of the first to third subpixels (C , C , C ).
