Abstract
A semiconductor device includes a plurality of light emitting elements formed of a thin layer of a compound semiconductor and arranged in a row in one direction with an equal interval therebetween. Each of the light emitting elements includes a light emitting area formed on a surface thereof; a first conductive type side electrode formed on the surface and electrically connected to one side of the light emitting element; and a second conductive type side electrode formed on the surface and electrically connected to the other side of the light emitting element. Further, the first conductive type side electrode is disposed at a position continuously surrounding at lease two sides of the light emitting area of the light emitting area with an insulating film inbetween. The second conductive type side electrode is disposed on the light emitting area.
