Abstract A biological characteristic identification device comprises a substrate, a light sensing piece layer on the substrate, and a light angle control layer and a light transmitting layer on the substrate. The light sensing element layer is provided with a light sensing element. The light angle control layer has a first light shielding layer and a second light shielding layer. The first shading layer is provided with a light-transmitting area which is partially overlapped with the light sensing part. The light transmitting layer is located on the light sensing element layer. The light-transmitting layer is provided with a convex part which is partially overlapped with the light sensing element and the first light shielding layer. The second light shielding layer is arranged on the top surface and the side surface of the convex part, the second light shielding layer and the first light shielding layer form an opening facing the other side surface of the convex part, the second light shielding layer is vertically pro
