  • Patent number: 10489628
    Abstract: A fingerprint recognition device, a method for fabricating the same, and a display device are disclosed. The first electrically conductive connection member is arranged between the drain of the TFT and photosensitive members, and the photosensitive members are connected with the drain of the TFT through the first electrically conductive connection member. Even when the surface of the drain becomes rough after first vias are formed in the insulating layer, it is the first electrically conductive connection member that is electrically connected with the photosensitive members. The first electrically conductive connection member has a smooth surface. This prevents the effect of formation of first vias in the insulating layer on the optical property of photosensitive members, thus improving performance of the fingerprint recognition device.
