Patent ID: 7102290

Claim:
A discharge light-emitting device comprising: a transparent first substrate; at least two first electrodes formed on said first substrate in parallel to each other and configured to form a first clearance between the at least two first electrodes, the first clearance extending in a longitudinal direction of said first substrate; a transparent second substrate; at least two second electrodes formed on said second substrate in parallel to each other and configured to form a second clearance between the at least two second electrodes, the second clearance extending in a longitudinal direction of said second substrate; sidewalls configured to form a discharge space with said first substrate, and said second substrate opposite to said first substrate so that said at least two first electrodes and said at least two second electrodes are opposite to each other and the at least two second electrodes are inside said discharge space; at least two first fluorescent layers formed on a discharge space side of said first substrate in parallel to each other so as to be opposite to said at least two first electrodes relative to said first substrate and configured to form a third clearance between the at least two first fluorescent layers, the third clearance extending in the longitudinal direction of said first substrate; and at least two second fluorescent layers formed on a discharge space side of said second substrate in parallel to each other so as to correspond to said at least two second electrodes and configured to form a fourth clearance between the at least two second fluorescent layers, the fourth clearance extending in the longitudinal direction of the second substrate, wherein light emitted from said at least two of first and second fluorescent layers on both sides of the third and fourth clearances is reflected from an original located on a side of said second substrate opposite to the discharge space side, and the reflected light passes through the third and fourth clearances and reaches a side of the first substrate opposite to the discharge space side.
