<P>PROBLEM TO BE SOLVED: To provide a light-emitting element which can obtain a light-emitting device which can emit a light-emitting wavelength with desired color in high power and has superior weather resistance, and to provide a light-emitting device provided with the element. <P>SOLUTION: The light-emitting element has a semiconductor structure 11 which has a light emitting layer 8; a light-extracting surface 18 which is provided in one main surface side of the semiconductor structure 11; and an electrode 3, which is provided in the other main surface side of the semiconductor structure 11 and electrically connected to the semiconductor structure 11. A reflecting structure 4 is formed between the semiconductor structure 11 and the electrode 3. The reflecting structure 4 is composed of a first reflective layer 4a, which reflects the center wavelength, corresponding to the wavelength of the light from the light-emitting layer 8, and a second reflecting layer 4b which sets the wavelength different from the center wavelength as the center wavelength. At least either of the center wavelength of the first reflecting layer 4a or the second reflective layer 4b is in visible light region. <P>COPYRIGHT: (C)2009,JPO&INPIT |
