Abstract
The present invention provides a display substrate, which includes an anode layer, a cathode layer and a luminous layer that is provided between the anode layer and the cathode layer, the anode layer including a plurality of anodes and the luminous layer including a plurality of luminous regions, wherein the display substrate further includes at least one assisting electrode, the assisting electrode being insulated and spaced from the anode, and the assisting electrode contacting with the cathode layer in parallel, such that a total resistance of the assisting electrode and the cathode layer connected in parallel is smaller than a resistance of the cathode layer alone. The IR drop in the cathode of the display substrate provided by the present invention is relatively small, such that loss of electric signals is relatively small in the cathode layer and the assisting electrode, thereby obtaining a relatively higher image quality.
