Abstract
An organic light-emitting display panel having a display area and a non-display area surrounding the display area and includes a base substrate, an organic light-emitting layer, a pixel definition layer, and a microlens layer that are located in the display area is disclosed. The organic light-emitting layer is located at a side of the base substrate and includes light-emitting units. The pixel definition layer includes first openings, and each light-emitting unit is located in one of the first openings. The microlens layer is located at a side of the pixel definition layer facing away from the base substrate and includes at least one first microlens. An orthogonal projection of the first microlens on the base substrate is located between orthogonal projections of two adjacent first openings on the base substrate.
