Manufacturing method of organic electroluminescent device, organic electroluminescent device, substrate for organic electroluminescent device and electronic apparatus

To provide an organic electroluminescent device capable of realizing reduction of wiring resistance, of reducing power consumption, of suppressing power generation, and of uniforming luminance; to provide a manufacturing method of the organic electroluminescent device; and to provide an electronic apparatus. This manufacturing method is used for manufacturing this organic electroluminescent device 1 provided with a luminescent function layer 47 surrounded by a first barrier rib 42a and a second barrier rib 45 on a first electrode 41a. The manufacturing method is characterized by comprising: a process for forming a first electrode material 41 and a first barrier rib material 42 on an inter-layer insulation film 30; a process for forming the first electrode 41a and the first barrier rib 42a by patterning the first electrode material 41 and the first barrier rib material 42 with masks PR having the same shape; and a process for forming the second barrier rib 45 on the inter-layer insulation film 30 and the first barrier rib material 42.
