Abstract
An organic light-emitting display panel has a display area and a non-display area and includes a base substrate, an organic light-emitting layer arranged at a side of the base substrate and including a plurality of light-emitting units, a pixel definition layer including a plurality of first openings, and a microlens layer arranged at a side of the pixel definition layer facing away from the base substrate and including at least one first sub-microlens. One light-emitting unit of the plurality of light-emitting units is located in one of the plurality of first openings. One first sub-microlens of the at least one first sub-microlens protrudes along a direction from the base substrate to the microlens layer. An orthogonal projection of one first sub-microlens of the at least one first sub-microlens on the base substrate overlaps with an orthogonal projection of the pixel definition layer on the base substrate.
