Abstract: Related to the field of display panels, an array substrate, a manufacturing method thereof, and a display panel. The array substrate includes: the base substrate, the buffer layer, the active layer, the gate insulation layer, the gate, the interlayer insulation layer, the source, and the drain, which are stacked together. By using the gate insulation layer as a conductive mask of the active layer, and by adjusting the width of the gate and the width of the gate insulation layer, a width difference between the channel region and the gate is within the preset range, which reduces the problem of excessive width difference caused by the diffusion phenomenon of the channel region, and can at the same time meet the switching characteristics requirements of the thin film transistor and the definition requirements of the display panel.
