Abstract
An organic EL element includes a pixel electrode, a light emitting function layer that is formed on the pixel electrode, an electron injection layer formed on the light emitting function layer, and a counter electrode that is formed on the electron injection layer and that has semi-transmissive reflectivity, in which the counter electrode contains a reductive material that reduces material of the electron injection layer and Ag with atomic ratio of 75% or more, and an adsorption layer is formed on the counter electrode.
