| 摘要 | A semiconductor light-emitting element includes a semiconductor layer including a light-emitting layer, and an upper reflective surface and a lower reflective surface between which the semiconductor layer is interposed. A distance L between the upper reflective surface and the lower reflective surface satisfies 0.20λ+0.5aλ≦L≦0.30λ+0.5aλ, where λ denotes a peak wavelength of light emitted from the light-emitting layer within the semiconductor layer, and a denotes an arbitrary positive integer. | ||
