Organic electroluminescent device, method of manufacturing the same, and electronic apparatus

A method of manufacturing an organic electroluminescent device in which a plurality of small electroluminescent substrates are connected to each other in a surface direction to form a large electroluminescent substrate, each of the plurality of small electroluminescent substrates including electrodes opposite to each other, a plurality of partitions formed between the small electroluminescent substrates, organic electroluminescent elements provided between the electrodes, each organic electroluminescent element including a functional layer having at least a light emitting layer, and driving elements to drive the organic electroluminescent elements, the method comprising:

• exposing end portions of at least one kind of wiring lines among wiring lines of the driving elements formed respectively on the plurality of small electroluminescent substrates;
• connecting the small electroluminescent substrates to each other such that the exposed end portions are opposite to each other;
• forming a plurality of partitions between the small electroluminescent substrates;
• arranging a conductive material between the end portions of opposing wiring lines, the wiring lines being formed below the plurality of partitions, to electrically connect the wiring lines to each other by the conductive material, formed below the plurality of partitions, in a plurality of joining portions between the small electroluminescent substrates.
