To provide an electroluminescent device capable of emitting light with sufficiently high luminance even when applied to a large-area display of 0.25 m 2 or more, ensuring good driving efficiency and causing less reduction of luminance due to heat generation, the electroluminescent device contains: a transparent conductive film; a light-emitting layer containing a phosphor particle and a binder; and a back electrode, wherein the transparent conductive film has a surface resistivity of 0.05 to 50 Ω/□, the light-emitting layer has an average thickness of 1 to 25 μm, and the back electrode comprises a metal. |
