Patent ID: 7002183

Claim:
A display unit including an array of a plurality of semiconductor devices, each device comprising: a base body; a selection mask formed on the base body, the selection mask defining a stripe-shaped opening having long-sides; a semiconductor layer formed by selective growth from the opening such as to have a ridge line substantially parallel to the long-sides of the opening, wherein the semiconductor layer is a wurtzite type compound semiconductor layer, and each of a pair of crystal planes located on both the sides of the ridge line is one of a (1-101) plane and a (11-22) plane; and a first conductive type cladding layer, an active layer, and a second conductive type cladding layer formed on the semiconductor layer, wherein the second conductive type cladding layer is formed on the pair of crystal planes, and an electrode is formed in a region of the second conductive type cladding layer that excludes a portion near the ridge line and that is located on the pair of crystal planes, and which has regular crystal steps.
