A display panel includes a plurality of rows of pixels, a gate driving circuit, and an inspection circuit. The gate driving circuit includes a plurality of gate driving units. The inspection circuit includes a plurality of transistors. Each transistor includes a first terminal, a control terminal, and a second terminal. The first terminal of the transistor is coupled to a contact pad. The control terminal of the transistor is coupled to the corresponding gate driving unit and a corresponding row of pixels. The second terminal of the transistor is coupled to the control terminal of the transistor.
