Abstract

The invention discloses a display panel, a display device and a manufacturing method of the display panel, and the display panel comprises a plurality of thin film transistors, and a plurality of fingerprint recognition elements, and each thin film transistor comprises a grid electrode, a source electrode, a drain electrode and an active layer; each fingerprint identification element comprises a first semiconductor part, a second semiconductor part, an insulating part and an electrode part. The first semiconductor part and the active layer are arranged on the same layer, the second semiconductor part is located on the side, away from the substrate, of the first semiconductor part, the insulating part is located on the side, away from the substrate, of the second semiconductor part, the electrode part is located on the side, away from the substrate, of the insulating part, the first semiconductor part is made of polycrystalline silicon, and the second semiconductor part is made of amorphous silicon. By constructing the fingerprint identification elements of the MIS structure, the photosensitivity of the fingerprint identification element is improved, the manufacturing cost of the display panel is reduced, the fingerprint identification precision is improved, and the manufacturing process of the display panel is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a display device and a method for manufacturing the display panel. Background technique [0002] In a display device provided by the prior art, the fingerprint identification element adopts polysilicon material, and the photosensitivity of polysilicon material is poor, so when polysilicon material is used as the fingerprint identification element, the fingerprint identification element needs a strong light source, and the existing The display device provided by the technology is usually unable to provide a light source with sufficient light intensity for the fingerprint identification element due to reasons such as display effect and high energy consumption, resulting in low accuracy of the fingerprint identification element. Contents of the invention [0003] In view of this, the present invention provides a display panel, including: an array...
