The invention provides an organic electroluminescent device, a method of manufacturing the organic electroluminescent device, and an electronic apparatus in which it is possible to make an entire display device compact as well as to reduce the manufacture cost. An organic electroluminescent device includes organic electroluminescent elements that each have a light-emitting layer between an anode and a cathode and that are formed on a substrate. The device includes lead-out wiring lines that are electrically connected to the cathodes.
