Plamsa display device and method for manufacturing the same

Abstract

A plasma display device includes a plasma display panel including an address electrode disposed on a first substrate, a pair of first and second display electrodes disposed on a second substrate and crossing the address electrode, a dielectric layer covering the first and second display electrodes on the second substrate, an MgO protective layer covering the dielectric layer on the second substrate, and discharge gases filled between the first and second substrates; a driver that drives the plasma display panel; and a controller that controls the driver so that a sustain pulse width of a sustain period is 1 to 3.5 μs, wherein a statistical delay time (Ts) depending on temperature is represented by the following Formula 1. y=A×e−kx   Formula 1 wherein k is a constant in a range of less than or equal to 2000 and a unit of the k is an absolute temperature (K), x is an reciprocal of the temperature (1/K), y is an reciprocal of a statistical delay time (Ts) (1/ns), and A is a constant ranging from 1×10−6 to 1×106. The MgO protective layer may be formed by MgO deposition in which a water vapor partial pressure of the deposition atmosphere is in a range of from 2×10−7 to 6×10−7 Torr·l/s. The plasma display panel lessens the temperature dependency of the discharge characteristics so that the response speed is improved and the discharge stability is improved.
