The invention discloses an electric connection structure which is positioned on the edge of a flexible display. The electric connection structure comprises a flexible substrate, a first line layer, anorganic buffer layer, an organic grid separating layer and an organic protective layer, wherein the first line layer is positioned on the flexible substrate and extends to the edge of the flexible substrate, the organic buffer layer is positioned on the flexible substrate and the first line layer, so that the first line layer is positioned between the organic buffer layer and the flexible substrate, the organic grid separating layer is positioned on the organic buffer layer, the organic protective layer is positioned on the organic grid separating layer, and each of the organic protective layer, the organic grid separating layer and the organic buffer layer has two through holes, so that the first line layer is positioned partially in the through holes. Since the first line layer of the electric connection structure is positioned on the flexible substrate, instead of organic material, the adhesion force of the first line layer is improved.
