To provide a new organic EL element in which an advantage of a low molecular weight material and an advantage of a polymeric material are sufficiently utilized, and its manufacturing method, a display device using them, and its manufacturing method.

This manufacturing method includes a process of laminating a first organic compound layer 121 on a first electrode 111 formed on a substrate 101 by vacuum depositing a material which contains an organic low molecular weight compound (L) of which the molecular weight is less than 1,000 as the main component, and does not contain a compound of which the molecular weight is 1,000 or more, and a process of forming a second organic compound layer 122 on the first organic compound layer 121 by coating a liquid containing an organic polymer compound of which the molecular weight is 1,000 or more. A dissolved amount of the organic low molecular weight compound (L) in a liquid medium 1 kg of the liquid is less than 1 mg at temperature of 25C.
