Abstract: The present disclosure discloses an array substrate and a display device including thereof. The array substrate includes a substrate, a shield metal over the substrate and a thin film transistor including an active layer with a channel region over the shield metal and a thermal gradient portion in at least one of the shield metal, the active layer and the array substrate so as to lower a temperature of a first area of the channel region than a temperature of a second area of the channel region. A cooling zone between the channel region and the shield metal is defined by the thermal gradient portion. The array substrate and a display device including the array substrate including the thermal gradient portion that defines the cooling zone between the thin film transistor and the shield metal can improves Kink effect, maintain high driving voltage, increase on current and/or improve switching properties.
