Abstract
A light emitting element array substrate includes a plurality of light emitting elements arranged in line on the substrate with less dispersion in irradiation to a surface to be irradiated and can be manufactured with a reduction of cost. The light emitting element array substrate also includes light reflecting members formed on the light emitting element array substrate about light emitting elements having less irradiation. The light reflecting members re-reflect the light emitted from the light emitting elements and also reflected by surrounding parts so that the quantity of light at portions of the light emitting element array substrate having less irradiation is complemented by the re-reflected light to level the entire irradiation in the light emitting element array substrate.
