Title:
SWITCH ELEMENT AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2021/046734
Kind Code:
A1
Abstract:
A switch element (10) and a corresponding display panel. The switch element (10) comprises: a substrate (11) and a gate electrode (GE), a gate insulation layer (13), a multi-layer structure, a source electrode (SE), a drain electrode (DE), and a passivation layer (19) all arranged on the substrate (11). The multi-layer structure comprises an active layer (15) and an interface layer (17) located on the side of the active layer (15) away from the substrate; the active layer (15) includes an oxide semiconductor material, and the interface layer (17) includes a polyhydroxy transition metal complex; the gate insulation layer (13) is located on one side of the multi-layer structure, and the gate electrode (GE) is located on the side of the gate insulation layer (13) away from the multi-layer structure; the source electrode (SE) and the drain electrode (DE) are located on the side of the multi-layer structure away from the substrate (11), and each electrically connect to the multi-layer structure; and the passivation layer (19) covers the side of the source electrode (SE) and the drain electrode (DE) away from the interface layer (17). By arranging the interface layer (17) on the side of the active layer (15) away from the substrate (11), the stability of the components of the switch element (10) can be improved.
