Abstract: 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.

Abstract: The present invention discloses an array substrate, a method of manufacturing the array substrate and a display device. Since the respective surfaces of the sources, the drains and the data lines are clad by the respective insulating films, in formation of the patterns of the pixel electrodes above the insulating films by using a patterning process, the insulating films can prevent the sources and the data lines provided under them from being corroded by an etching agent when an etching process is performed to form the patterns of the pixel electrodes, so as to avoid an influence on display quality of a display panel. Furthermore, since the insulating films are formed by curing the insulating material, instead of the photoresist, remained on the patterns of the sources, the drains and the data lines when forming the patterns of the sources, the drains and the data lines by using the insulating material (replacing the photoresist), formation of the insulating films will not increase the number of masks, and a step of peeling off the insulating material is omitted. Furthermore, the respective connecting portions electrically connects the respective drains with the respective pixel electrodes through the respective first via holes A located above the respective drains and passing through the respective insulating films, so that a normal display function of the display panel can be ensured.
