Abstract

An organic light-emitting display panel and a preparation method therefor, and a display apparatus. The organic light-emitting display panel comprises: a substrate; a plurality of organic light-emitting diodes, wherein the plurality of organic light-emitting diodes are located on the substrate, and each of the organic light-emitting diodes is provided with a first electrode, a second electrode, and a light-emitting layer and a hole injection layer which are located between the first electrode and the second electrode; and anti-crosstalk isolation electrodes, wherein each of the anti-crosstalk isolation electrodes is located at a gap between two adjacent organic light-emitting diodes, the anti-crosstalk isolation electrodes are configured to connect to a fixed voltage, and a voltage difference between each anti-crosstalk isolation electrode and each second electrode is less than a voltage difference between each first electrode and each second electrode.
