An electrical connection structure providing better optical properties in a display includes an electrical connection unit, an interference layer, and an electrically insulating cover. The interference layer is positioned on a side of the electrical connection unit. The electrically insulating cover is positioned on the other side of the electrical connection unit and formed to cover the electrical connection unit. The electrical connection unit includes a metal layer to reflect light. The interference layer reflects light emitted from the electrically insulating cover towards a first side of the interference layer. A degree of reflectance of the first side of the interference layer is equal to the reflectance of the metal layer.
