Claim 3:
4. The display panel according to claim 2, wherein the angle is greater than or equal to a second angle θ1 and less than or equal to a third angle θ2; the second angle θ1 is greater than the first angle θ;
θ1=arctan((c−d)/a), θ2=arctan((b−e)/a);
where a is a first distance, b is a second distance, d is a third distance, e is a fourth distance, c is a fifth distance;
the first distance a is a difference between a minimum distance from the light reflection layer to the base substrate and a maximum distance from the imaging pinhole to the base substrate;
in a case that the organic light emitting layer of the sub-pixel in the display panel is placed in a horizontal direction, the second distance b is a sum of a shortest distance between an orthographic projection of the organic light emitting layer on the base substrate and an orthographic projection of the imaging pinhole on the base substrate, and a width of the imaging pinhole;
in a case that the organic light emitting layer is placed in the horizontal direction, the third distance d is a shortest distance between an orthographic projection on the base substrate of an intersection point of first light, which is emitted to the light reflection layer from an uppermost end of the organic light emitting layer, and the light reflection layer, and the orthographic projection on the base substrate of the organic light emitting layer;
in a case that the organic light emitting layer is placed in the horizontal direction, the fourth distance e is a shortest distance between an orthographic projection on the base substrate of an intersection point of second light, which is emitted to the light reflection layer from a lowermost end of the organic light emitting layer, and the light reflection layer, and the orthographic projection on the base substrate of the organic light emitting layer;
the fifth distance c is a shortest distance between the orthographic projection of the organic light emitting layer on the base substrate and an orthographic projection of the imaging pinhole on the base substrate;
in a case that the organic light emitting layer is placed in the horizontal direction, the first light is emitted to the light reflection layer, and reflected by the light reflection layer to become first reflection light which is emitted to a first end of the imaging pinhole;
in a case that the organic light emitting layer is placed in the horizontal direction, the second light is emitted to the light reflection layer, and reflected by the light reflection layer to become second reflection light which is emitted to a second end of the imaging pinhole; a distance between an orthographic projection of the second end of the imaging pinhole on the base substrate and the orthographic projection of the organic light emitting layer on the base substrate is greater than a distance between an orthographic projection of the first end of the imaging pinhole on the base substrate and the orthographic projection of the organic light emitting layer on the base substrate.
