    摘要： It is an object of the present invention to provide a light emitting element which can reduce defective operation due to crystallization of a compound. One of the light emitting elements of the present invention has a layer, which generates electrons, between a first electrode and a second electrode. The layer generating electrons includes a phenanthroline derivative represented by the general formula (1) and a metal oxide. The metal oxide shows an electron donating property to the phenanthroline derivative represented by the general formula (1). Herein, in the general formula (1), R1 to R5 individually represents an alkyl group having 1 to 4 carbon atoms or a halogen group, and further at least one of R1 to R5 represents a halogen group.

    摘要： Light-emitting elements have a problem that their light-extraction efficiency is low due to scattered light or reflected light inside the light-emitting elements. The light-extraction efficiency of the light-emitting elements needs to be enhanced by a new method. According to the present invention, a light-emitting element includes a first layer generating holes, a second layer including a light-emitting layer for each emission color and a third layer generating electrons between an anode and a cathode, and the thickness of the first layer is different depending on each layer including the light-emitting layer for each emission color. A layer in which an organic compound and a metal oxide are mixed is used as the first layer, and thus, the driving voltage is not increased even when the thickness is increased, which is preferable.
