Abstract

An array substrate, a display panel, and a display apparatus are provided. The array substrate includes a substrate and a first thin-film transistor located on the substrate. In an embodiment, the first thin-film transistor includes a channel and a gate electrode. In an embodiment, an orthographic projection of the gate electrode on the substrate overlaps with an orthographic projection of the channel on the substrate. In an embodiment, the gate electrode comprises a first zone and a second zone that are arranged in a first direction. In an embodiment, the channel overlapping with the first zone in a direction perpendicular to the substrate has a total width Win a second direction perpendicular to the first direction, the channel overlapping with the second zone in a direction perpendicular to the substrate has a total width Win the second direction, and W/W≤3.
