1. A display device comprising:
- pixels positioned in regions demarcated by scan lines and data lines;
a scan driver including a plurality of stages connected to the scan lines;
an inspection unit connected to the stages to detect whether the stages are defective, and including first transistors turned on when a control signal is supplied; and
a timing controller supplying the control signal,wherein the timing controller detects a position of a defective stage by reducing a period during which the control signal is supplied.

6. A display device comprising:
-
pixels positioned in regions demarcated by scan lines and data lines; a scan driver including stages connected to the scan lines; an inspection unit including first transistors respectively connected to the stages to detect whether the stages are defective and second transistors respectively connected to the first transistors and turned on in response to receiving a control signal; and a timing controller supplying the control signal, wherein the timing controller detects a position of a defective stage by reducing a period during which the control signal is supplied. - View Dependent Claims (7, 8, 9)

10. A method of inspecting a display device including stages for supplying a scan signal, the method comprising:
-
setting first transistors respectively connected between a detect line and the stages to an ON state by supplying a control signal; and inspecting whether the stages are defective by using a voltage supplied to the detect line, wherein in response to a determination that at least one of the stages is defective, a position of the defective stage is detected by reducing a supply period of the control signal. - View Dependent Claims (11, 12)
