摘要:
It is an object to provide a light-emitting element having high light-emitting efficiency, which includes a first electrode, a second electrode, and a light-emitting layer between the first electrode and the second electrode, where the light-emitting layer contains a base material, a first impurity element, a second impurity element, and an organic compound; the base material is an inorganic compound containing an element belonging to Group 2 and an element belonging to Group 16 of the periodic table, or an inorganic compound containing an element belonging to Group 12 and an element belonging to Group 16 of the periodic table; the first impurity element is any of copper (Cu), silver (Ag), gold (Au), platinum (Pt), arsenic (As), phosphorus (P), or palladium (Pd); and the second impurity element is any of fluorine (F), chlorine (Cl), bromine (Br), iodine (I), boron (B), aluminum (Al), gallium (Ga), indium (In), or thallium (Tl).
