Abstract
The present embodiment relates to a semiconductor light-emitting element or the like including a structure for suppressing deterioration in the quality of an optical image caused by an electrode blocking a part of light outputted from a phase modulation layer. The semiconductor light-emitting element includes a phase modulation layer having a basic layer and a plurality of modified refractive index regions, and the phase modulation layer includes a first region at least partially overlapping the electrode along a lamination direction and a second region other than the first region. Among the plurality of modified refractive index regions, only one or more modified refractive index regions in the second region are disposed so as to contribute to formation of an optical image.
