Abstract: A display device including a display panel that includes a pad electrode, a data driver disposed on the display panel and including a bump electrode that corresponds to the pad electrode, and an adhesive layer that includes a nano-conductive particle in contact with the pad electrode and the bump electrode. The pad electrode includes a dielectric pattern that protrudes more than the surroundings of the pad electrode, a conductive pattern that covers the dielectric pattern, and a dielectric layer that covers the conductive pattern. The nano-conductive particle penetrates the dielectric layer to contact the conductive pattern.
