PROBLEM TO BE SOLVED: To provide an EL element that facilitates manufacturing of cathode partition-walls so as to simplify alignment between each EL light-emitting pixel and each light-collecting lens.;SOLUTION: An EL element manufacturing method includes a photosensitive resin forming step, in which a plurality of transparent anodes, patterned corresponding to display pixels and a lens sheet having a plurality of light-extraction lens elements which are arrayed opposite to the plurality of anodes are, respectively provided and a photosensitive resin layer is formed on the plurality of anodes opposite to the lens sheet; and a partition-wall forming step in which the photosensitive resin layer is exposed and developed through the plurality of lens elements to thereby remove the photosensitive resin layer on the anodes, corresponding to the display pixels and to form each partition wall on the upper face of each anode by each part of the remaining photosensitive layer.;COPYRIGHT: (C)2010,JPO&INPIT
