The invention discloses an organic light-emitting display panel and a manufacturing method thereof, and relates to the technical field of display, and the organic light-emitting display panel provided by the invention mainly improves the structure of a first electrode layer connected with an auxiliary electrode. A containing hole used for containing the organic layer is formed in the face, back on to the array substrate, of the first electrode layer. When an organic layer is coated with a solution, a flowing organic material can flow into the accommodating hole to form the organic layer, so that the second electrode layer can be directly connected with the first electrode layer, the impedance between the auxiliary electrode and the cathode layer is further improved, the influence of the organic layer with relatively poor conductivity is avoided, and the service life of the battery is prolonged. And the display uniformity of the organic light-emitting display panel is improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting display panel and a manufacturing method thereof. Background technique [0002] Organic light emitting devices (Organic Light Emitting Diode, OLED) have been widely used in the fields of display, lighting, and smart wear due to their good self-luminous characteristics, high contrast, and fast response. [0003] An organic light emitting display panel generally includes an array substrate, an anode layer disposed on the array substrate, an organic layer disposed on the anode layer, and a cathode layer disposed on the organic layer. Wherein, when a large-sized organic light-emitting display panel is in operation, different degrees of voltage drop will be generated at different positions of the cathode layer due to the relatively high resistance of the cathode layer. Therefore, at present, organic light-emitting display panels generally have auxiliary ele...
