A small-sized semiconductor light-emitting device of high emission directivity
and high output is provided. A portion of a light extraction section of a semiconductor
light-emitting device including a pn-junction portion is covered with a light-shielding
substance of low conductivity. The electrical resistance of the light-shielding
substance is 106 m or higher, and the substance contains powder
of at least one species selected from metals and pigments. The powder of metal
contains at least one species selected from among Al, Cu, Ag, Au, Pt, Ti, Ni, Sn,
Pb, Mg, Zn, Fe, Co, and Cr. The powder is a plate-like powder having a thickness
falling within a range of 0.001-10 m and a length falling within a range
of 0.01-100 m.
