A gate driver is constituted of a first gate driver including a first shift register that is configured by bistable circuits corresponding to gate bus lines on odd-numbered lines arranged on one side of a display portion, and a second gate driver including a second shift register that is configured by bistable circuits corresponding to gate bus lines on even-numbered lines arranged on another side of the display portion. A first buffer circuit is provided on one end side of each gate bus line, and a second buffer circuit is provided on another end side of each gate bus line. A control signal for controlling the scanning order of the gate bus line is given to the bistable circuit and the second buffer circuit.
