Abstract: An array substrate and a display panel are provided. The array substrate includes transistors. Each transistor includes an active portion and a first gate, and the active portion is disposed on the substrate. The active portion includes at least one semiconductor portion and at least one epitaxial sharp corner portion connected to the semiconductor portion and protruding from the semiconductor portion in a first direction. In the first direction, the epitaxial sharp corner portion is located on one side of the semiconductor portion, the first gate is located on the semiconductor portion and the epitaxial sharp corner portion, and the first gate extends along the first direction.

Abstract: A display panel, display device, and driver chip are provided. A non-display area of the display panel comprises a bonding area comprising a first bonding area. The first bonding area comprises a horizontal bonding area and a first oblique bonding area comprising a first end and a second end. A distance from the second end to the display area is greater than a distance from the first end to the display area of the display panel. A plurality of bonding terminal groups of the first oblique bonding area are arranged in a stepped-shape manner at equal intervals or unequal intervals.
