<p>The purpose of the present invention is to provide a method for manufacturing organic EL elements whereby organic EL elements, which are suitable for lighting that is resistant to leakage current and short circuiting, are manufactured by laser processing without using expensive photolithography. This method for manufacturing organic EL elements is provided with: a step for forming a first electrode (2) in a divided manner on a substrate (1); a step for forming an insulation film (5) so as to be adjacent to the first electrode (2), which corresponds to an area that is in contact with a second electrode (4) of an adjacent light-emitting element; a step for forming a first dividing groove (8) by removing an organic light-emitting layer (3) laminated above the first electrode (2), which corresponds to an area that is in contact with a second electrode (4) of an adjacent light-emitting element, by laser processing; a step for forming the second electrode (4) so as to fill the first dividing groove (8) and cover a plurality of the organic light-emitting layers (3); and a step for forming a second dividing groove (11), the bottom surface of which is the insulation film (5), by removing the organic light-emitting layer (3) and the second electrode (4) laminated above the insulation film (5), by laser processing.</p> |
