Electroluminescence device and display device

A method of manufacturing an organic electroluminescence device, the organic electroluminescence comprising one or more organic layers including a luminescent layer between an anode and a cathode and emitting light generated in the luminescent layer from the cathode,

• the method comprising the steps of:
• forming the anode comprising silver (Ag) or an alloy including silver on a substrate;
• forming a thin film layer for hole injection made of a material with a higher work function than that of the anode on the anode in an atmosphere of an inert gas;
• forming the one or more organic layers including the luminescent layer on the thin film layer for hole injection;
• and
• forming the cathode on the organic layer.

• the method comprising the steps of:
• forming the anode comprising silver (Ag) or an alloy including silver on a substrate;
• forming a thin film layer for hole injection made of a material with a higher work function than that of the anode on the anode by use of an area mask with an aperture corresponding to an area where the thin film layer for hole injection is intended to be formed;
• forming the one or more organic layers including the luminescent layer on the thin film layer for hole injection;
• and
• forming the cathode on the organic layer.
