摘要：
It is an object of the present invention to provide a light-emitting element capable of reducing malfunction due to oxidation and crystallization of a compound. According to one aspect of the present invention, a light-emitting element has a first electrode and a second electrode, a first layer and a second layer formed between the first electrode and the second electrode, wherein the first layer contains an anthracene derivative and a substance that shows electron acceptability to the anthracene derivative, wherein the second layer contains a light emitting substance. According to one aspect of a light-emitting device of the present invention, any one of the above light-emitting elements is used as a pixel or a light source.
