This invention provides an organic electroluminescent element comprising a substrate and an electrode and one or more organic layers provided on the substrate. The organic electroluminescent element is characterized in that the layer density of at least one of the organic layers is 1.10 to 1.25 g/cm. The organic electroluminescent element exhibits good luminescence brightness, causes no significant voltage rise and dark spot in the constant-current driving, and has good temporal stability under high temperature and high humidity conditions. There are also provided a display device and a lighting device using the organic EL element.

A layer forming method is disclosed which comprises the steps of supplying power of not less than 1 W/cmat a high frequency voltage exceeding 100 kHz across a gap between a first electrode and a second electrode opposed to each other at atmospheric pressure or at approximately atmospheric pressure to induce a discharge, generating a reactive gas in a plasma state by the charge, and exposing a substrate to the reactive gas in a plasma state to form a layer on the substrate.

Layer forming method, product comprising the layer, optical film, dielectric-coated electrode and plasma discharge apparatus

A dielectric-coated electrode having a conductive base material coated with a dielectric on a surface thereof, the dielectric including a first metal atom and a second metal atom. As for an ionic strength of the first metal atom and an ionic strength of the second metal atom according to a dynamic SIMS measurement, the ionic strength of the second metal atom is larger than the ionic strength of the first metal atom from the most surface of the dielectric toward a predetermined depth of the dielectric, and the ionic strength of the first metal atom is larger than the ionic strength of the second metal atom from the predetermined depth toward the surface of the conductive base material.
