It is an object of the present invention to provide a light emitting element that realizes a high contrast. It is another object of the present invention to provide a light emitting device that realizes a high contrast by using the light emitting element with an excellent contrast. The light emitting element has a layer containing a light emitting substance interposed between a first electrode and a second electrode, and the layer containing the light emitting substance includes a light emitting layer, a layer containing a first organic compound, and a layer containing a second organic compound. The first electrode has a light-transmitting property, and the layer containing the first organic compound and the layer containing the second organic compound are interposed between the second electrode and the light emitting layer. Furthermore, color of the first organic compound and color of the second organic compound are complementary.
