ABSTRACT:
In a production process of a thin film laminate for constituting an organic EL element or the like, a thin film laminate is provided in which no water stays in a thin film formed of a hydrophilic material and, thus, the function of other thin films overlying the surface of the thin film, such as a luminescent layer, is not deteriorated. The thin film laminate comprises: a substrate; and, provided on the substrate in the following order, a first thin film and a second thin film. The first thin film is formed of a hydrophilic organic material. The hydrophilic organic material has hydrophilic groups which have been converted to lipophilic group. The lipophilic groups are partially or wholly returned to hydrophilic groups upon exposure to heat energy or a radiation. The second thin film is formed of a lipophilic organic material.
