<p><P>PROBLEM TO BE SOLVED: To suppress a variation of brightness to the same printing information among light emitting elements. <P>SOLUTION: A light emitting apparatus comprises a light emitting element part 18 in which a plurality of organic EL elements are arranged in a line as the light emitting elements 11, and lighting circuits 19 equipped with circuit elements connected with the light emitting elements, selectively emitting light by time sharing on a prescribed number of the light emitting elements based on a selective signal, a driving signal and a holding signal, and provided to respective light emitting elements. A prescribed number of the lighting circuits connected with prescribed number of the light emitting elements are arranged adjoiningly in the vertical direction to the arranging direction of a prescribed number of the light emitting elements. A wiring length adjusting part 21 is connected with wiring connecting the lighting circuits with the light emitting elements. The total wiring lengths of anode wiring 20 and the wiring length adjusting parts connecting the lighting circuits with the light emitting elements are made equal in all the lighting circuits, and the areas and the number of intersecting parts between the anode wiring and the wiring length adjusting parts with the other wiring are made the same in all the lighting circuits. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
