US Patent 7977881 Plasma display panel

A plasma display panel is provided. The plasma display panel includes a front substrate including an upper dielectric layer, a rear substrate including a lower dielectric layer, and a seal layer between the front substrate and the rear substrate. A length of a longer side of the front substrate is longer than a length of a longer side of the rear substrate, and a length of a shorter side of the front substrate is shorter than a length of a shorter side of the rear substrate. An interval between an end of the front substrate and an end of the upper dielectric layer in a direction crossing the longer side of the front substrate is less than an interval between an end of the front substrate and an end of the upper dielectric layer in a direction crossing the shorter side of the front substrate.
