Abstract
Provided is a display device including a display panel including a sub-pixel connected to a data line and a reference line, a driving circuit configured to supply a data voltage to the display panel through the data line, and a sensing circuit including a sampling circuit for sensing the display panel through the reference line, wherein the sampling circuit includes a sampling switch having a turn-on state within an image display period of the display panel to acquire a sensing voltage by sensing the reference line and determine presence or absence of a defect based on the sensing voltage.
