摘要： A thin-film transistor includes a substrate, and a light-shielding layer and an active layer sequentially over the substrate. The light-shielding layer has an accommodating space having a bottom wall and a side wall on an upper surface thereof. An orthographic projection of the active layer on the substrate is contained within an orthographic projection of the accommodating space of the light-shielding layer on the substrate. An upper side of the side wall of the accommodating space of the light-shielding layer has a larger distance to the substrate than a bottom surface, and optionally has an equal or larger distance to the substrate than a top surface, of the active layer. The light-shielding layer can comprise a gate electrode. As such, lights from an underneath and from a lateral side of the thin-film transistor that otherwise reach the active layer can be partially or completely blocked.
