Assignee: BOE TECHNOLOGY GROUP CO., LTD.
Field: Micro-structural and nano-technology (Chemistry)
Classification: CPC B | IPC B

Claim 0:
1. A micro-nano channel structure, comprising:
a base substrate;
a base layer, on the base substrate and comprising a plurality of protrusions; and
a channel wall layer, on a side of the plurality of the protrusions away from the base substrate, and the channel wall layer is provided with a micro-nano channel;
wherein a recessed portion is provided between adjacent protrusions of the plurality of the protrusions, and an orthographic projection of the micro-nano channel on the base substrate is located within an orthographic projection of the recessed portion on the base substrate;
the micro-nano channel is on a side of the protrusions away from the base substrate, and an orthographic projection of the micro-nano channel on a plane perpendicular to a main surface of the base substrate is partly overlapped with or not overlapped with an orthographic projection of the corresponding protrusions on the plane perpendicular to the main surface of the base substrate.
