Patent attributes
In order to provide a light emitting device and an electronic equipment which suppress luminance deterioration, and have long life, the invention does not form an organic compound layer which is composed of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer and so on, and electrodes in vacuum-through, as in a conventional vacuum deposition method, but after a hole injection layer, which comprises phthalocyanine, is formed, it is exposed to gas atmosphere. In particular, copper phthalocyanine is exposed to oxygen atmosphere. By this method, provided is an organic light emitting element which has long life, and by using the above-described organic light emitting element, a light emitting device and an electronic equipment are fabricated.
