Abstract: Embodiments of this application disclose a display panel and a preparation method thereof, and an electronic device, and relate to the field of display technologies, to improve display brightness uniformity of a display panel. The display panel includes: a backplane, an anode layer and a transfer electrode that are located on the backplane, a light emission function layer and a cathode layer that are located on the anode layer and the transfer electrode and that are sequentially stacked, a cathode suppression layer, and an auxiliary cathode. The backplane includes an auxiliary signal line, configured to reduce a voltage drop of the cathode layer. The transfer electrode and the anode layer are disposed on a same layer, and the transfer electrode is electrically connected to the auxiliary signal line. The light emission function layer and the cathode layer are provided with a first opening.
