The present application provides a display panel and a method for preparing same. A fingerprint identification module and a storage capacitor of a display panel are disposed in a thin film transistor device layer, and the fingerprint identification module is electrically connected to an active layer of a thin film transistor and the storage capacitor by means of an electrode layer, thereby optimizing the structure of an array substrate. In addition, the display panel can better receive a reflected light signal, the fingerprint identification performance is good, the preparation process is simple, and the panel production cost is low.
