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.

Abstract: A backlight module and a display device. The backlight module includes a light source, a light guide plate, and a connection layer; the connection layer is sandwiched between the light source and the light guide plate, and is in contact with the light source and the light guide plate respectively; the connection layer is formed based on a viscous material and is configured to transmit light emitted by the light source, which can achieve the buffering effect through the viscous material of the connection layer, and the light source will not produce adverse effects even if being squeezed. Further, the gap between the light source and the light guide plate can also be filled by the connection layer, which is approximately equivalent to making the light source being closer to the light guide plate.
