Abstract
The present invention provides a method for manufacturing a light-emitting element that can be driven with low voltage or utilizes current more efficiently without damaging an organic compound, and a light-emitting element formed by the method. According to the present invention, a rubbing treatment is performed on a surface of an electrode on which an organic layer is formed so as to control a molecular arrangement of an organic compound included in the organic layer. A second electrode is formed over the organic compound.
