1. A display device comprising:
a first conductive layer arranged on a first substrate and extending in a first direction;
a first insulating film arranged on the first conductive layer;
a second conductive layer arranged on the first insulating film and extending in a second direction intersecting the first direction;
a second insulating film arranged on the second conductive layer and extending in the first direction and the second direction;
a first transparent conductive layer arranged on the second insulating film and extending in the first direction and the second direction;
a third insulating film arranged on the first conductive layer; and
a second substrate opposing the first substrate,
wherein the second insulating film has a first protrusion protruding above a surface of the first transparent conductive layer,
a first opening surrounding the first protrusion is arranged in the first transparent conductive layer,
a second opening surrounding the first protrusion is arranged in the third insulating film, and
the first protrusion is arranged to maintain a gap between the first substrate and the second substrate.
