Abstract
The display device includes a display panel, gate line driving circuitry that includes gate drivers provided for each of gate lines, a control circuit, and a signal processing circuit. The control circuit supplies a control signal to at least one gate driver corresponding to a gate line to be scanned first in a unit period in which the gate lines are scanned. The gate driver which received the control signal is driven on the basis of the control signal, and the gate drivers in subsequent stages are each driven on the basis of a scanning signal of the gate driver in a preceding stage. The signal processing circuit outputs, on the basis of a scanning signal of at least one gate driver corresponding to a gate line to be scanned last in the unit period and the control signal, a detection signal that indicates whether the gate driver is normal.
