Abstract
A biometric identification device is provided. Photosensitive devices are disposed on the substrate. The first dielectric layer is disposed on the photosensitive devices. The first light-shielding parts are disposed on the first dielectric layer. Each of the first light-shielding parts has a first light-transmitting area and a first light-shielding area surrounding the first light-transmitting area. The first light-transmitting area corresponds to and overlaps with the photosensitive device, and at least two of the first light-shielding parts are spaced apart by a spacer area. The second dielectric layer is disposed on the first light-shielding parts. The second light-shielding part is disposed on the second dielectric layer. An orthogonal projection of at least a part of the spacer area on the substrate is within an orthogonal projection of a second light-shielding area on the substrate.
