Display device

A display device comprising:

• a plurality of pixel electrodes being apart from each other;
• a carrier injection/transport layer stacked on the plurality of pixel electrodes across the plurality of pixel electrodes;
• a plurality of light emitting layers positioned on an opposite side of the carrier injection/transport layer from the plurality of pixel electrodes, each of the plurality of light emitting layers being above each of the pixel electrodes;
• a common electrode which covers the plurality of light emitting layers;
• and
• underlayers which are in contact with the carrier injection/transport layer and are positioned on an opposite side of the carrier injection/transport layer from the light emitting layer,
• wherein each of the plurality of pixel electrodes has an upper surface positioned at a side of the carrier injection/transport layer,
• at least a part of the upper surface is a flat portion,
• the underlayers include the plurality of pixel electrodes,
• a first surface of the underlayer has an irregular shape, the first surface being in contact with the carrier injection/transport layer,
• a second surface of the carrier injection/transport layer is flat, the second surface positioned at a side of the light emitting layer,
• each of the light emitting layers faces the flat portion of each of the pixel electrodes, and
• a thickness of each of the light emitting layers is uniform directly above the flat portion.
