Plasma display panel

Abstract

A plasma display panel capable of stabilizing a discharge characteristic by integrating discharge cells with a high density and efficiently exhausting the plasma display panel is provided. The plasma display panel is constructed with: first and second substrates facing each other; barrier ribs disposed between the first and second substrates to define discharge cells; address electrodes extending in a first direction and corresponding to the discharge cells; and first and second electrodes extending in a second direction that crosses the first direction and corresponding to the discharge cells. The red, green, and blue discharge cells among the discharge cells are disposed in a triangular shape. Exhaust paths are formed between neighboring discharge cells.
