Abstract

A display device includes: a display region, a frame region, a thin-film transistor layer, and a light emitter layer including a plurality of light emitters each having a first electrode, a light-emitting layer, and a second electrode. The plurality of light emitters emits mutually different colors of light. The second electrode is shared among the plurality of light emitters and contains a metal nanowire. The frame region includes a bank having a frame shape surrounding the display region and defining an end of the second electrode. A conductive film is disposed closer to the display region than the bank is, the conductive film electrically connecting together the terminal section and the second electrode. The conductive film includes a contact portion being in contact with the metal nanowire. The contact portion has a plurality of asperities disposed on a contact surface being in contact with the metal nanowire.
