Abstract: The present PDP includes a rear plate, a plurality of barrier ribs on the rear plate, and a front plate in parallel with the rear plate. The front plate includes a transparent dielectric layer, a plurality of joint notches on the transparent dielectric layer, and a protective layer on the transparent dielectric layer that covers the joint notches. The position of each of the joint notches is aligned with the position of one corresponding barrier rib, and each joint notch has a filler to affix within the joint notch corresponding the barrier rib. When the front plate is mounted onto the rear plate, the top of each of the barrier ribs of the rear plate is pushed through the protective layer and is embedded in the corresponding joint notch of the front plate. The filler within each of the joint notches fills the gap between the top of the barrier rib embedded in the joint notch and the joint notch so that the front plate is tightly fixed to the rear plate.
