1. A display device, comprising:
a first substrate that includes a first electrode;
a second substrate disposed under the first substrate and that includes a second electrode that overlaps the first electrode; and
an anisotropic conductive film disposed between the first substrate and the second substrate, wherein the anisotropic conductive film includes an insulating resin layer and a plurality of conductive particles disposed in the insulating resin layer,
wherein the conductive particles include first conductive particles that overlap the first electrode and the second electrode, and second conductive particles other than the first conductive particles,
wherein each of the first conductive particles and the second conductive particles includes a first flat surface, a second flat surface that faces the first flat surface, and a curved surface rounded between the first flat surface and the second flat surface, and
wherein a first length of each of the first conductive particles and the second conductive particles in a first direction from the first substrate to the second substrate is less than a second length of each of the first conductive particles and the second conductive particles in a second direction orthogonal to the first direction.
