Classification: CPC H  G | IPC G  H

Claim 19:
20. A display device, comprising a display panel, wherein
the display panel comprises a display panel, and
the array substrate comprises:
a substrate;
a plurality of sub-pixels on the substrate, wherein each sub-pixel comprises a pixel circuit, the pixel circuit comprises a plurality of transistors, and the plurality of transistors comprises at least one oxide transistor;
an oxide semiconductor layer on the substrate, wherein the oxide semiconductor layer comprises a channel region of the oxide transistor;
a first planarization layer on the substrate and covering at least a portion of the oxide semiconductor layer, wherein the first planarization layer comprises a recessed region, and at least a portion of an orthographic projection of the recessed region on the substrate is located outside an orthographic projection of the channel region of the oxide transistor on the substrate; and
a barrier part on a side of the first planarization layer away from the substrate, wherein at least a portion of an orthographic projection of the barrier part on the substrate overlaps an orthographic projection of the channel region of the oxide transistor on the substrate, an orthographic projection of the barrier part on the substrate overlaps at least a portion of an orthographic projection of the recessed region on the substrate, and the barrier part is filled in the recessed region.
