Display device

A display device comprising:

• a display region having a plurality of pixels;
• and
• a frame region around the display region,
• wherein the display region includes, in listing order, a substrate, a thin-film transistor layer, a light emitter layer having a plurality of light emitters configured to emit mutually different colors of light, and a sealing layer sealing the light emitter layer,
• the plurality of light emitters include, in listing order on the substrate, a first electrode, a hole transportation layer, an emissive layer, an electron transportation layer, and a second electrode,
• either one of the first electrode and the second electrode is an island-shaped electrode provided for each of the plurality of light emitters,
• the other one of the first electrode and the second electrode is a common electrode shared among the plurality of light emitters, and
• the electron transportation layer contains an oxide nanoparticle, a binder resin, and a photo-initiator.
