PROBLEM TO BE SOLVED: To provide an organic electroluminescent element capable of driving at low voltage, and provide a light source and the like utilizing the feature as a plane light-emitting body such as a backlight source for a low-power-consumption flat panel display for an OA computer or a wall-mounted television, a display board, a marker lamp, a copier, a liquid crystal display, and gauges.;SOLUTION: An organic electroluminescent element includes at least an anode, a hole injection transport layer, a light-emitting layer, and a cathode in this order. The hole injection transport layer includes an organic film containing the following compounds (A) and (B) at the same time: (A) arylamine polymer with a weight average molecular weight of 10000 or more and 5000000 or less; and (B) a compound without a cross-linking group with a molecular weight of 5000 or less.;COPYRIGHT: (C)2013,JPO&INPIT
