Abstract
A light-emitting diode () has a main light-extracting surface and includes a compound semiconductor layer () including semiconductor layers (to), a light-emitting part () contained in the compound semiconductor layer, a light-emitting layer () contained in the light-emitting part, a transparent substrate () joined to the compound semiconductor layer, and first and second electrodes () of opposite polarities formed on the main light-extracting surface on the side opposite the transparent substrate. The second electrode is formed at a position on the portion of the compound semiconductor layer exposed by removing the semiconductor layers (to) and has the periphery thereof enclosed with the semiconductor layers. The main light-extracting surface has an external shape having the largest width of 0.8 mm or more.
