Display device

A display device comprising:

• a substrate;
• a switching element provided on the substrate and including a relay electrode;
• a first lower electrode provided further away from the substrate than the switching element, the first lower electrode having an outer edge;
• a first insulating film provided on the first lower electrode;
• a first middle electrode provided on the first insulating film, the first middle electrode connected to the relay electrode through a through hole of the first insulating film;
• a second insulating film provided on the first middle electrode;
• and
• a first upper electrode provided on the second insulating film and supplied with a same potential as that of the first lower electrode, the first upper electrode including a plurality of openings,
• wherein
• the first middle electrode functions as a pixel electrode,
• the first lower electrode and the first upper electrode sandwich the first middle electrode and function as a common electrode,
• the through hole is provided outside the outer edge of the first lower electrode,
• an entirety of the thorough hole is covered with the second insulating film and the first upper electrode, and
• the second insulating film includes a filler disposed to fill in the through hole, and a first layer covering the through hole and the filler.
