The recessed structure is between the chip-on-film bonding region and a lateral side of the array substrate. The chip-on-film bonding region is between the display region and the lateral side. By disposing a recessed structure configured to fill the bonding material in the peripheral region, a gap is difficult to occur between the chip-on-film in the chip-on-film bonding region and the array substrate, preventing entry of water vapor to cause corrosion of lead wires and short circuits of lead wires. The defect ratio of the array substrate, the display panel, and the display device is reduced, and the product quality is improved.
