<p><P>PROBLEM TO BE SOLVED: To provide an exposure device with a lens array, which sets an interval between the lens array and an organic EL element to a sufficiently narrow value, and sufficiently improves the reliability thereof. <P>SOLUTION: The exposure device is formed of a plurality of light emitting elements 14, an element substrate 20 on which the light emitting elements 14 are arranged, and a plate-like sealing body 30 making contact with the element substrate 20 to seal the light emitting elements 14. The sealing body 30 defines a closed space SP inclusive of the light emitting elements 14 in cooperation with the element substrate 20. Then each of micro-lenses L makes contact with inert gas filled in a cavity C in the closed space SP and overlaps each light emitting element 14 in a direction perpendicular to the element substrate 20. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
