The present invention discloses an organic electroluminescent display panel, comprising: a base substrate; a top-emitting type organic electroluminescent structure located on the base substrate, the organic electroluminescent structure comprising an anode, a light emitting layer and a cathode arranged in this order from the base substrate; and a packaging film covering the organic electroluminescent structure; the organic electroluminescent display panel further comprises a secondary electrode provided on the packaging film and electrically connected with the cathode through a via hole penetrating through the packaging film. Since the secondary electrode is additionally provided on the packaging film and is electrically connected with the cathode through the via hole penetrating through the packaging film, the secondary electrode electrically connected with the cathode can increase an equivalent thickness of the cathode and thus reduce the resistance of the cathode, which can avoid the problem of large voltage drop due to large resistance of the cathode when a thinner metal is used as the cathode, thereby can avoid damage of the organic electroluminescent display panel due to the larger voltage drop.
