Abstract: The present application relates to the technical field of display, and discloses a display panel, a preparation method therefor, and a display apparatus. The material of a filter film layer in the display panel comprises a conductive material, so the filter film layer may be used as a detection plate of a fingerprint identification circuit. Moreover, since the filter film layer is located on the side of a display function film layer away from a base substrate, the filter film layer is far away from a signal line in the display function film layer, and is not easily affected by the signal line. When the filter film layer is used as the detection plate, the signal-to-noise ratio of a fingerprint signal detected by the fingerprint identification circuit may be larger, and the fingerprint identification effect may be better. Moreover, when the filter film layer is used as the detection plate, the distance between the filter film layer and an obstacle relative to the display function film layer is relatively short. Therefore, the signal detected by the fingerprint identification circuit may be made larger, thereby ensuring the fingerprint identification effect.
