<p>PROBLEM TO BE SOLVED: To solve the problem that an emission intensity is varied by a dimensional irregularity of each electroluminescence, etc., in a light source using the electroluminescence as a light emitting medium. SOLUTION: One light source is constituted of a plurality of light emitting parts, whereby an amount of the variation of the emission intensity is reduced, and at the same time, shading can be corrected easily.</p> |
