Plasma display device having an improved contrast radio

2A plasma display device is realized which has a high set-luminous-efficacy (i.e. provides a high-brightness display image at a low power consumption) and a high light-room contrast. The luminous efficacy hs and the display discharge voltage Vs are increased by increasing the product pd in discharge...

Summary:2A plasma display device is realized which has a high set-luminous-efficacy (i.e. provides a high-brightness display image at a low power consumption) and a high light-room contrast. The luminous efficacy hs and the display discharge voltage Vs are increased by increasing the product pd in discharge, or increasing the Xe proportion aXe of the discharge. As a result the display-discharge region area ratio Ad and the display region reflectance β can be reduced by reducing the display-electrode area Sse approximately in inverse proportion to Vs, and thereby the set-luminous efficacy hs and the set luminance Bpons and the light-room contrast Cb are increased.
