Abstract (en)

[origin: WO2012172258A1] The invention relates to a substrate bearing an OLED electrode, having a sheet resistance of less than 25 O/?, comprising: an electrically conductive coating; a thin essentially inorganic electrically conductive film that acts as a work function matching layer, having a sheet resistance at least 20 times higher than the sheet resistance of the electrically conductive coating and a thickness of at most 60 nm; and, between the electrically conductive coating and the work function matching layer, an essentially inorganic thin film, called a buffer film, having a contact resistivity lying in the range from 1×10-6 to 1 O·cm2 .
