Abstract
The present disclosure provides a display panel and a manufacturing method thereof, and a display device. The display panel includes a base substrate, a light shielding layer and a pixel definition layer which are provided on the base substrate in turn; the light shielding layer includes an imaging pinhole; the display panel further includes a plurality of fingerprint recognition sensors arranged in an array, the fingerprint recognition sensors are provided on the base substrate; the light shielding layer is provided on a light incoming side of the fingerprint recognition sensors; a minimum distance between the imaging pinhole and the organic light emitting layer in the red sub-pixel is less than a minimum distance between the imaging pinhole and the organic light emitting layer in the green sub-pixel and is also less than a minimum distance between the imaging pinhole and the organic light emitting layer in the blue sub-pixel.
