First Claim
1. A flat illumination light, comprising:
- a plurality of discharge electrodes formed on a first substrate with an interval between adjacent discharge electrodes being set to 50 μ
m or smaller;
a reflective layer and a fluorescent layer formed on a second substrate opposite said first substrate; and
a sealed vessel formed by said first and second substrates so that said electrodes and said fluorescent layer are located on inner sides of said first and second substrates, wherein gasses of one or more kinds of He, Ne, Ar, Xe and Kr are introduced into said sealed vessel so that a pressure of said introduced gasses is above 1.0 atmospheric pressure.

Abstract
A plurality of discharge electrodes (23), (24) are formed on a first substrate (22) at an interval between the adjacent electrodes set to 50 μm or smaller. A fluorescent layer (26) is formed on a second substrate (25 opposed to the first substrate (22). A sealed vessel (28) is formed by locating the first and second substrates (22) and (25) so that the electrodes (23) and (24) and the fluorescent layer (26) should be located on their inner sides. A predetermined gas is introduced in the sealed vessel (28) so that a pressure of the introduced gas should be within the range from 0.8 to 3.0 atmospheric pressure. Ultraviolet rays are produced by plasma discharge and make the fluorescent layer (26) emit light which is employed as illumination light.
