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 10<SUP>6 </SUP>Omegam 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 mum and a length falling within a range of 0.01-100 mum. |
