    • A plasma display device such that fluctuation of discharge start voltage and lowering of luminance would not easily occur, the burning phenomenon of the screen is suppressed, and excellent reliability and long life can be secured, and a method of producing the same, are disclosed. The plasma display device comprises a first panel (10) provided with discharge sustaining electrodes (12) and a dielectric layer (14) on the inside thereof, and a second panel (20) laminated on the first panel (10) so that discharge spaces (4) are formed on the inside of the first panel (10), and the trap density and/or the movable metallic ion density in the dielectric layer (14) is not more than 1×1018 pieces/cm3, preferably not more than 1×1017 pieces/cm3.
    • 等离子体显示装置不会容易发生放电开始电压的波动和亮度的降低,屏幕的燃烧现象被抑制,并且可以确保优异的可靠性和长的使用寿命,并且公开了其制造方法。 等离子体显示装置包括在其内部设置有放电维持电极(12)和电介质层(14)的第一面板(10)和层叠在第一面板(10)上的第二面板(20),使得放电空间 (4)形成在第一面板(10)的内部,并且电介质层(14)中的陷阱密度和/或可动金属离子密度不大于1×10 18个/ 3/3,优选不超过1×10 17个/ cm 3以上。
