Abstract

The embodiment of the invention discloses a display device. The display device comprises a display functional layer, a fingerprint identification module, at least one functional layer and at least one adhesive layer, wherein the display function layer comprises a first area and a bending area which are arranged in the first direction, and the first area comprises a first sub-area; at least one functional layer comprises at least one first functional layer, at least one adhesive layer comprises at least one first adhesive layer, the first functional layer is in contact with the first adhesive layer, and one side, facing the first adhesive layer, of the first functional layer is provided with at least one first groove; the orthographic projection of the first groove on the plane where the display function layer is located is located between the first sub-area and the bending area, so that the probability that the parallel relation between the first sub-area of the display function layer and the binding face of the fingerprint recognition module is damaged in the repeated bending process of the display device is reduced, and the fingerprint identification precision of the fingerprint identification module based on the received light or sound wave characteristics is improved.
