Abstract
Semiconductor light-emitting devices (10, 30, 40) in which the directivity of intensity and color tone of exit light is small and the light output does not decrease easily. The semiconductor light-emitting devices comprise semiconductor light-emitting elements (1, 31), and thin film light diffusion portions (8, 8a, 38, 41) arranged on the light exit direction side of the semiconductor light emitting elements.
