Display panel and display device

A display device, comprising:

• a display panel comprising:
• an array substrate, having a first substrate and a plurality of light-emitting units on the first substrate;
• an encapsulation layer, disposed on a side, facing away from the first substrate, of the plurality of light-emitting units;
• and
• a fingerprint recognition module disposed on the encapsulation layer and comprising at least one fingerprint recognition unit, wherein
• a projection of the fingerprint recognition unit onto the array substrate is located within a non-light-emitting area of the first substrate, and the non-light-emitting area is located between two adjacent light-emitting units;
• and a horizontal distanced d between an edge of the fingerprint recognition unit and an edge of a closest light-emitting unit from the fingerprint recognition unit is greater than or equal to a preset distance so that the display panel has a viewing angle being greater than or equal to 50°;
• when the encapsulation layer is a transparent rigid cover plate and the fingerprint recognition module is disposed under the transparent rigid cover plate, the preset distance is h*tan ψ;
• and
• when the encapsulation layer is a thin film encapsulation layer and the fingerprint recognition module is disposed on a surface, facing away from the array substrate, of the thin film encapsulation layer, then the preset distance is

• wherein h represents a vertical distance from the fingerprint recognition unit to a light-exiting side of a light-emitting layer of the light-emitting unit, and w represents the viewing angle.
