Claim 17:
18. A manufacturing method of a texture recognition device, comprising:
providing a backlight component;
providing a photosensitive component which is configured to detect light emitted by the backlight component and reflected by a texture of a detection object to recognize an image of the texture of the detection object, wherein the photosensitive component comprises a plurality of photosensitive sensors and an antistatic layer on a side, away from the backlight component, of the plurality of photosensitive sensors, and orthographic projections of the plurality of photosensitive sensors on a plane where the antistatic layer is located are within the antistatic layer; and
stacking the backlight component and the photosensitive component,
wherein the backlight component comprises a surface light source and a light restriction layer,
the light restriction layer is on a side, close to the photosensitive component, of the surface light source, and is configured to restrain light emitted from the surface light source to a direction perpendicular to a surface of the texture recognition device.
