Objects of the present invention are to provide a light-emitting element that does not readily deteriorate, a light-emitting device and an electronic device that do not readily deteriorate, and a method of fabricating the light-emitting element that does not readily deteriorate. A light-emitting element having an EL layer between a pair of electrodes is covered with a layer containing an inorganic compound and halogen atoms or a layer containing an organic compound, an inorganic compound, and halogen atoms, whereby deterioration by moisture penetration can be inhibited. Thus, a light-emitting element with a long life can be obtained.
