Abstract

A detection base plate and a flat-panel detector. The detection base plate comprises multiple detection pixel units arranged in an array. Each detection pixel unit comprises: a thin-film transistor, a sacrificial layer and a photoelectric conversion part that are disposed on a substrate, wherein the sacrificial layer is located between the thin-film transistor and the photoelectric conversion part; the thin-film transistor comprises an active layer, a first electrode and a second electrode; at least part of an orthographic projection of the active layer on the substrate is located within an orthographic projection of the sacrificial layer on the substrate; and the photoelectric conversion part is electrically connected to the sacrificial layer and the first electrode. In the detection base plate, the sacrificial layers of the detection pixel units are mutually independent.
