Abstract

In a flat display apparatus of this invention, which uses a discharge plasma, a UV discharge gas prepared by mixing Xe as a main discharge gas and Ne as a discharge control gas such that the partial pressure of Xe becomes, e.g., 15% is injected into a space between a display substrate and a counter substrate opposing the display substrate at a predetermined pressure. A plurality of first electrodes capable of specifying a position in the first direction on the substrate, a plurality of second electrodes capable of specifying a position in the second direction perpendicular to the first direction, and third electrodes (auxiliary electrodes) equal in number to the first or second electrodes are formed on at least one substrate at a predetermined interval. With this arrangement, the discharge start voltage required for initialization of the discharge generation portion (pixels between the substrates), a write in a memory, and discharge sustaining and memory erase operations can be set to be low.

Dependent claims

A flat type display apparatus using a plasma discharge, comprising:

a first substrate capable of passing visible light;
a second substrate opposed to said first substrate at a predetermined gap;
a discharge gas formed of Xe excluding a halogen sealed in said gap;
excitation means for exciting the discharge gas to generate UV rays, the excitation means including a first electrode arranged on a side of said first substrate opposing said second substrate, and a second electrode arranged on a side of said second substrate opposing said first substrate;
and
photoconversion means, including a phosphor layer formed on the second electrode, for emitting predetermined visible light on the basis of the UV rays, said phosphor layer including a first region emitting a red component of the visible light, a second region emitting a blue component of the visible light, and a third region emitting a green component of the visible light and wherein the thickness of the first, second and third regions are different,
wherein the discharge gas is caused by said excitation means to perform excimer light emission for generating UV rays.
