In order to provide a light emitting device which consistently emits light
at the time of continuous driving in addition to obtain light emission
having a high color purity in each of red, green and blue, a light
emitting element according to the present invention, in which an organic
compound film comprising a hole transporting material, an electron
transporting material, a first impurity (first doping material), and a
second impurity (second doping material) is provided between an anode and
a cathode, is characterized in that the organic compound film is
laminated with a first mixed region comprising the hole transporting
material and the first impurity, a hole transporting region comprising
the hole transporting material, a second mixed region comprising the
electron transporting material and the second impurity, and an electron
transporting region comprising the electron transporting material in
order from the side of the anode.
