A plasma display panel prevents electrostatic force between upper and lower substrates and noise and error discharge due to non-uniformity. The plasma display panel includes a lower substrate, a plurality of barriers formed on the lower substrate, an upper substrate, a dielectric layer formed on the upper substrate to have grooves of a predetermined depth along regions adjoining the barriers, and a plurality of ground electrodes formed between the barriers and the grooves of the dielectric layer, having both ends commonly connected to one another. Thus, it is possible to prevent noise of the product resulting from vibration of the upper and lower substrates from occurring and optimize the operation conditions, thereby improving quality of the product.
