In the organic electroluminescent element of the present invention, at least a first conductive layer, a charge injecting and transporting layer formed by a wet film-forming method, a light emitting layer, and a second conductive layer are laminated on a substrate, 1) The charge injection / transport layer includes a charge injection layer in contact with the first conductive layer, (2) the charge injection / transport layer has a thickness of 130 to 1000 nm, and (3) the charge injection layer is a crosslinked aromatic amine. Including polymers. The substrate is a glass substrate, and the minimum value of the undulation tangent of the surface of the glass substrate on the first conductive layer side is 4.00 × 10 −6 or more, or the maximum value of the undulation tangent is 22 × 10 −6 or more. . |
