A thin-film device includes a polysilicon element and an oxide semiconductor element. The polysilicon element includes a first part made of low-resistive polysilicon. The oxide semiconductor element includes a second part made of low-resistive oxide semiconductor. The first part and the second part are disposed to overlap each other and connected.

Thin-film device

A display panel includes a substrate and a plurality of pixel driving circuits disposed on the substrate, and the plurality of pixel driving circuits include a storage capacitor and transistors. The transistors include transistors of a first type and a second type. The transistor of the first type is a composite transistor and includes a first sub-transistor and a second sub-transistor that are connected in series. The first sub-transistor is a low-temperature polysilicon transistor, and the second sub-transistor is an oxide transistor. The transistor of the first type includes a composite active layer, a composite gate electrode, a composite source electrode, and a composite drain electrode. The composite source electrode or the composite drain electrode of the transistor of the first type is electrically connected to the storage capacitor, or the transistor of the first type is in an off state during a light-emitting phase.
