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.

Abstract: The present disclosure provides an anti-reflection film and a flexible display device. The anti-reflection film includes: a linear polarization film stretched in a first stretching direction; and a phase delay film stretched in a second stretching direction. When a light beam passes through the linear polarization film, the light beam is converted into a linear polarized light, and when the light beam passes through the phase delay film, the phase delay film changes a phase of the light beam. A first acute angle α is formed between the first stretching direction and the second stretching direction. The anti-reflection film has a folding axis, and a vertical line of the folding axis is located within the first acute angle α.

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.
