Display device and display device manufacturing method

A method of manufacturing a display device comprising:

• forming multiple first electrodes on a substrate;
• forming light-emitting layers including forming a first light-emitting layer on some of the multiple first electrodes, forming a second light-emitting layer on some other of the multiple first electrodes, and forming a third light-emitting layer on remains of the multiple first electrodes;
• providing a protruding portion in a region between the multiple first electrodes;
• after the providing a protruding portion, forming, on the protruding portion, a charge transfer layer including a thin film portion having a film thickness thinner than portions on the multiple first electrodes and a portion other than on the protruding portion in the region between the multiple first electrodes as a continuous film in a display region including the multiple first electrodes and the region between the multiple first electrodes on the substrate;
• and
• forming a second electrode.
