1. A semiconductor device comprising:
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,
wherein each of said light emitting elements includes:
a light emitting area formed on a first surface of the light emitting element;
a first conductive type side electrode formed on the first surface and electrically connected to one side of the light emitting element, said first conductive type side electrode being disposed at a position continuously surrounding at lease two sides of the light emitting area in a first direction that the light emitting elements are arranged and a second direction perpendicular to the first direction; and
a second conductive type side electrode formed on the first surface and electrically connected to the other side of the light emitting element, said second conductive type side electrode being disposed on the light emitting area.
