1. A display device comprising:
a thin film transistor layer;
a light-emitting, element including a first electrode, a function layer, and a second electrode;
a sealing layer; and
a touch panel layer including a lower layer electrode and a plurality of upper layer electrodes,
wherein the plurality of upper layer electrodes include a first upper layer electrode and a second upper layer electrode adjacent to the first upper layer electrode and electrically separated from the first upper layer electrode,
the lower layer electrode is provided in common with the first upper layer electrode and the second upper layer electrode and overlaps with the first upper layer electrode and the second upper layer electrode via an insulating film,
the first upper layer electrode includes a first protrusion protruding toward the second upper layer electrode, and the second upper layer electrode includes a second protrusion protruding toward the first upper layer electrode,
the first protrusion and the second protrusion face each other with a gap therebetween, and
the lower layer electrode is provided with a wide portion having a width greater than those of the first protrusion and the second protrusion, the wide portion overlapping at least with the gap.
