Abstract: A fingerprint identification module and a display device are disclosed. In the fingerprint identification module, a light shading layer above a photosensitive sensing unit includes a first light shading component above a photosensitive diode of the photosensitive sensing unit, and a fixed potential signal line. The first light shading component is electrically connected to a terminal of the photosensitive diode thereunder and connected to the fixed potential signal line. Since the fixed potential signal line is above the photosensitive diode, and the light shading layer is directly used to form the fixed potential signal line, connecting holes that need to occupy some space can be omitted, and the area occupied by the photosensitive diode can be maximized, thus the light current generated by the photosensitive diode during fingerprint detection can be increased so as to enhance fingerprint detection accuracy.
