Display device and method of manufacturing the same

A display device comprising:

• a substrate including a display area and a pad area;
• a plurality of pad electrodes disposed in the pad area on the substrate;
• a circuit board disposed to overlap at least a portion of the pad area on the substrate, wherein the circuit board includes a base substrate and a plurality of bump electrodes disposed on a lower surface of the base substrate;
• and
• an anisotropic conductive layer disposed in the pad area between the substrate and the circuit board, wherein the anisotropic conductive layer includes an adhesive layer and a plurality of conductive particles arranged in the adhesive layer,
• wherein each of the conductive particles includes a core, a first conductive film disposed on the core in a way such that at least a portion of the core is exposed, and a second conductive film entirely covering the core and the first conductive film, and
• wherein the first conductive film is a single conductive film continuously extending in a way such that a half portion or at least a half portion of the core is exposed.
