PROBLEM TO BE SOLVED: To provide a novel E having high luminous luminance and luminous efficiency Provided are an L element and a novel organic compound material for a light emitting layer for realizing such an EL element. An EL element according to the present invention includes a glass substrate, an ITO electrode as a transparent electrode, and a hole injection layer. And a hole-transporting light-emitting layer 4, an electron-transporting light-emitting layer 5, and a MgAg electrode 6 as a back electrode, which are stacked in this order. The hole transporting light emitting layer 4 is Tri (o-terphenyl-4-yl) amine and tri (p- (Terphenyl-4-yl) amine. The electron transporting light emitting layer 5 is 5,5 ′ It is made of an organic compound material -bis (dimesitylboryl) -2,2'-bithiophene. Further, the hole injection layer 3 is preferably made of an organic compound material of 4,4 ′, 4 ″ -tris (3-methylphenylphenylamino) triphenylamine. |
