Abstract: A light emitting display device can include a display panel configured to display an image; a driver configured to drive the display panel; a controller configured to control the driver; and a defect sensing circuit configured to sense a current through a driving voltage line transmitting a driving voltage for driving of the display panel, and output a sensing value based on the current for determining whether an element in a subpixel of the display panel is defective.
