Abstract
A display device includes a plurality of upper layer electrodes including a first upper layer electrode and a second upper layer electrode electrically separated from the first upper layer electrode, and a lower layer electrode provided in common with the first upper layer electrode and a second upper layer electrode and overlapping 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 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 a gap between the first protrusion and the second protrusion.
