1. A display device comprising:
a first substrate;
a second substrate opposed to the first substrate; and
a capacitance electrode, wherein
the first substrate comprises:
an insulating substrate;
a switching element located on the insulating substrate and having a relay electrode;
an organic insulating film covering the switching element, and having a first through-hole penetrating to the relay electrode;
a pixel electrode located between the organic insulating film and the second substrate, and being in contact with the relay electrode via the first through-hole;
a first capacitance insulating film covering the pixel electrode;
a filler having an insulation property filled in at least the first through-hole, and located on the pixel electrode and the first capacitance insulating film; and
a common electrode covering the filler,
the capacitance electrode located between the organic insulating film and the pixel electrode,
the pixel electrode extends on the capacitance electrode, and
the capacitance electrode does not overlap the first through-hole.
