Claim 13:
14. A manufacturing method of a display panel comprising red sub-pixels, green sub-pixels and blue sub-pixels; wherein the manufacturing method of a display panel comprises:
forming a light shielding layer and a pixel definition layer on a base substrate in sequence; opening regions arranged in an array being formed on the pixel definition layer; the light shielding layer comprising an imaging pinhole;
forming an organic light emitting layer in the opening region;
providing a light reflection layer on a side of the organic light emitting layer away from the light shielding layer;
providing a plurality of fingerprint recognition sensors arranged in an array on a side of the base substrate away from the light shielding layer;
setting a minimum distance between the imaging pinhole and the organic light emitting layer in the red sub-pixel to be less than a minimum distance between the imaging pinhole and the organic light emitting layer in the green sub-pixel;
setting the minimum distance between the imaging pinhole and the organic light emitting layer in the red sub-pixel to be less than a minimum distance between the imaging pinhole and the organic light emitting layer in the blue sub-pixel.
