PROBLEM TO BE SOLVED: To reduce surface irregularities of a sealing layer covering a light emitting element.SOLUTION: A plurality of light emitting elements 45 emitting light with the supply of drive current and a sealing body 70 covering each light emitting element 45 are formed on a surface of a substrate 10. The sealing body 70 comprises a lamination of a first sealing layer 71, a second sealing layer 72 and a third sealing layer 73. The second sealing layer 72 is formed of, for example, an organic material so as to have a sufficiently thick film thickness T as comparted with the first sealing layer 71 and the third sealing layer 73. The interval δX of each light emitting element 45, the pitch DX of each light emitting element 45, and the width WX of each light emitting element 45 are set to equal to or less than the film thickness T of the second sealing layer 72. |
