(57) [Summary] [Problem] It is easy to manufacture and drive, at low cost, Light-emitting elements with no restrictions on shape and size, light-emitting elements that can be used as surface light sources instead of point light sources, a wide range of optical gaps can be freely selected, have excellent light-emitting characteristics, high-speed response, environmental resistance and environmental resistance. To provide an optically active light emitting device having high temperature characteristics. SOLUTION: On a first electrode, at least Al, A light-emitting element comprising: a light-emitting layer formed of a non-single-crystal optical semiconductor containing at least one element selected from Ga and In and nitrogen; and a second electrode. |
