Claim 18:
19. An array substrate, comprising:
a substrate comprising a plurality of sub-pixel regions and a plurality of monochromatic light-emitting regions;
a thin film transistor located in each of the sub-pixel regions on the substrate, and the thin film transistor comprises a gate, an active layer, and a source-drain electrode;
a passivation layer located on a side, away from the substrate, of the thin film transistor;
a color resist located on a side, away from the substrate, of the passivation layer and located in the monochromatic light-emitting regions;
a planarization layer located on a side, away from the substrate, of the color resist and the passivation layer;
an anode located on a side, away from the substrate, of the planarization layer and electrically connected to a drain electrode in the source-drain electrode through a first through hole penetrating through the passivation layer and the planarization layer; and
dielectric layers located between the source-drain electrode and the substrate, wherein a thickness of at least one of the dielectric layers between the first through hole and the substrate is greater than a thickness of the at least one of the dielectric layers between the color resist and the substrate;
wherein the active layer in the thin film transistor is located between the gate and the substrate;
the dielectric layers comprise: an interlayer dielectric layer located between the source-drain electrode and the gate, and the drain electrode is electrically connected to the active layer through a third through hole penetrating through the interlayer dielectric layer;
orthographic projections of the third through hole and the first through hole on the substrate do not overlap; and
a thickness of the interlayer dielectric layer between the thin film transistor and the substrate is greater than a thickness of the interlayer dielectric layer between the color resist and the substrate.
