Abstract

The disclosure provides a display panel and a display device. The display panel includes a first substrate and a second substrate, the second substrate has an organic electroluminescent device, an anode layer of the organic electroluminescent device is away from the first substrate and a cathode layer thereof is closer to the first substrate than the anode layer; the cathode layer is electrically connected to an auxiliary electrode on a light entering surface of the first substrate through multiple conductive spacers, the cathode layer is a transparent electrode layer; the auxiliary electrode has a resistance smaller than that of the cathode layer of the organic electroluminescent device; the auxiliary electrode is a grid-shaped auxiliary electrode and in a non-display region, the auxiliary electrode is opaque; the multiple conductive spacers includes first conductive spacers on the auxiliary electrode and second conductive spacers on the cathode layer of the second substrate.
