1. A touch panel comprising a flat region, bending regions located on at least two adjacent sides of the flat region and a deformation region located between the adjacent bending regions; the flat region, the bending regions and the deformation region are provided with a touch control structure, and the deformation region is provided with at least two crack guide grooves; on a plane parallel to the touch panel, a shape of a crack guide groove comprises a strip shape extending along an extension direction, and extension directions of the at least two crack guide grooves intersect with each other,
wherein the adjacent bending regions comprise a first bending region extending in a first direction and a second bending region extending in a second direction; the deformation region comprises a first sub-region adjacent to the first bending region, a second sub-region adjacent to the second bending region, and a central sub-region between the first sub-region and the second sub-region, wherein the first direction intersects with the second direction; and extension directions of the crack guide grooves in the first sub-region, the second sub-region and the central sub-region intersect with each other; and
wherein a crack guide groove in the first sub-region has a strip shape extending along a first extension direction, and an included angle between the first extension direction and the first direction is 75 degrees to 105 degrees.
