Abstract:
To provide a novel light-emitting element or a highly reliable light-emitting element. To provide a light-emitting device, a display device, an electronic device, and a lighting device each of which can be manufactured at a low cost. To provide a light-emitting element including an anode, a cathode, and an EL layer between the anode and the cathode. The EL layer includes a light-emitting layer and an electron injection transport layer between the light-emitting layer and the cathode, and the amount of a halogen detected from a material forming the electron injection transport layer is less than or equal to 30 ppm.
