1. A displaying substrate, comprising an active area, wherein the active area comprises a plurality of luminous zones arranged in an array and a non-luminous zone located between the adjacent luminous zones;
the displaying substrate further comprising:
a first capacitor electrode at least partially located in the luminous zones;
a buffer layer covering the first capacitor electrode and located in the luminous zones and the non-luminous zone; and
a second capacitor electrode and an active layer that are disposed on the buffer layer and do not overlap with each other, the active layer being located in the non-luminous zone;
wherein, the first capacitor electrode, the buffer layer and the second capacitor electrode form a storage capacitor;
wherein the displaying substrate further comprises:
a gate disposed on and insulated from the active layer, located in the non-luminous zone, and electrically connected to the second capacitor electrode; and
an anode disposed on the second capacitor electrode and the gate, insulated from the second capacitor electrode and the gate, at least partially located in the luminous zones, and electrically connected to the first capacitor electrode and the active layer.
