OLED LIGHT-EMITTING DEVICE, DISPLAY DEVICE, ELECTRONIC DEVICE, AND METHOD OF MANUFACTURING OLED LIGHT-EMITTING DEVICE

A first stack-structured light-emitting element includes light-emitting units and a first charge generation layer between the light-emitting units. A second stack-structured light-emitting element includes light-emitting units and a second charge generation layer between the light-emitting units. Each of the first and second charge generation layers consists of one or more charge generation component layers. A first end region of the first charge generation layer and a second end region of the second charge generation layer overlap above the top face of the element separation layer. In the overlap region, an end region of a component layer of the first or second stack-structured light-emitting element configured to block charges of either polarity is interposed between charge generation component layers of the first and second charge generation layers configured to generate charges of the same polarity as the charges to be blocked by the component layer.
