Semiconductor light emitting element and manufacturing method thereof

A semiconductor light-emitting device (LE1) comprises a multilayer structure LS generating light. This multilayer structure includes a plurality of laminated compound semiconductor layers (3 to 8) and has first and second main faces (61, 62) opposing each other. A first electrode (21) and a second electrode (31) are arranged on the first and second main faces, respectively. A film made of silicon oxide (10) is also formed on the first main face so as to cover the first electrode. A glass substrate (1) optically transparent to the light generated by the multilayer structure is secured to the multilayer structure through the film made of silicon oxide.
