Organic electroluminescence element

An organic electroluminescence element comprising:

• a first electrode made of an electrically conductive and light transmissive material;
• a light emitting layer formed on the first electrode by use of an organic material;
• a second electrode formed on the light emitting layer by use of an electrically conductive material;
• a first terminal part which is placed on a first end of the light emitting layer in a first direction crossing a thickness direction of the light emitting layer and is electrically coupled to the first electrode;
• a second terminal part which is placed on a second end of the light emitting layer in the first direction and is electrically coupled to the second electrode;
• and
• an auxiliary electrode which is formed on the first electrode so as to be located beside the light emitting layer in a second direction crossing the thickness direction and the first direction and is electrically coupled to the first electrode,
• wherein:
• the auxiliary electrode is formed into an elongated shape extending in the first direction by use of a material having a specific resistance smaller than that of the first electrode;
• and
• the auxiliary electrode includes plural portions with different thicknesses such that a sheet resistance is increased with an increase in a distance from the first terminal part in a lengthwise direction of the auxiliary electrode.
