Array substrate and manufacturing method thereof, and a display device

摘要

An array substrate is provided. The array substrate includes a substrate body, a gate electrode layer, a first insulating layer, a source-drain electrode layer, a second insulating layer, and a transparent conducting layer, wherein the transparent conducting layer includes a bridging part. The bridging part includes a first electrode, a second electrode, and a connecting electrode, wherein a reference plane is defined perpendicular to the substrate body and passing through the first electrode, the connecting electrode, and the second electrode, and wherein a cross-sectional area of the connecting electrode that is taken perpendicular to the reference plane and taken perpendicular to the substrate body is i) smaller than a cross-sectional area of the first electrode and ii) smaller than a cross-sectional area of the second electrode.
