Beschreibung
Zusammenfassung:	The embodiment of the invention discloses a display panel, a display device and a preparation method of the display panel. The display panel comprises a first substrate base plate; a plurality of fingerprint identification units located at one side of the first substrate; a plurality of collimation hole units which are located at sides, deviating from the first substrate, of the fingerprint identification units; each collimation hole unit comprises at least one layer of shading part; each shading part is provided with a light through hole; the vertical projections of the light through holes ofthe shading parts on the plane where the first substrate is located are at least partially overlapped; a collimation hole is formed in the area where each light through hole is located; the verticalprojections of the collimation holes on the plane where the first substrate is located are at least partially overlapped with the vertical projections of the fingerprint identification units on the plane where the first substr
