摘要： The concentration of oxygen, which causes problems such as decreases in brightness and dark spots through degradation of electrode materials, is lowered in an organic light emitting element having a layer made from an organic compound between a cathode and an anode, and in a light emitting device structured using the organic light emitting element. The average concentration of impurities contained in a layer made from an organic compound used in order to form an organic light emitting element having layers such as a hole injecting layer, a hole transporting layer, a light emitting layer, an electron transporting layer, and an electron injecting layer, is reduced to 5×1019/cm2 or less, preferably equal to or less than 1×1019/cm2, by removing the impurities with the present invention. Formation apparatuses are structured as stated in the specification in order to reduce the impurities in the organic compounds forming the organic light emitting elements.
