Abstract: A fingerprint recognition apparatus including a frontplane, a backplane and a display medium layer is provided. The frontplane includes an upper substrate, a black matrix layer, a color filter layer, and a plurality of filtering elements. The black matrix layer is disposed on the upper substrate, and the color filter layer is disposed on the black matrix layer. The black matrix layer includes a plurality of pixel apertures and a plurality of first apertures. The filtering elements cover the first apertures and the filtering elements. The backplane includes a lower substrate and a sensor layer. The sensor layer includes a plurality of photo sensing elements. The photo sensing elements are configured to receive reflected lights from an object through the first apertures and the filtering elements. Areas of the photo sensing elements are overlapped with the first apertures in a longitudinal direction. The display medium layer is disposed between the frontplane and the backplane.
