1. A display device, comprising:
a driving element substrate including a plurality of driving elements of a pixel;
a circuit board disposed on a first surface of the driving element substrate in a first direction;
a cover substrate disposed to overlap the driving element substrate on a second surface of the driving element substrate in a second direction opposite to the first direction, wherein the cover substrate includes a protrusion protruding from the driving element substrate to an outside in a third direction intersecting to the first direction, and the cover substrate further includes a connection line;
a conductive spacer disposed between the driving element substrate and the cover substrate to electrically connect the driving element substrate and the cover substrate; and
a circuit film including a first end connected to the protrusion of the cover substrate and a second end connected to the circuit board and opposite to the first end,
wherein the conductive spacer has a structure in which a conductive material is surrounded by polyimide.
