Abstract
Official abstract text for this publication.
A display device, which can prevent defects in a drive power transmission line and damage which is caused to a common electrode by such defects, and a method for detecting line defects of the display device are provided. The display device includes a plurality of drive power transmission lines for transmitting drive power to pixels, at least one defect detection line that crosses at least one drive power transmission line, and a defect detector for outputting a defect detection signal to the at least one defect detection line, collecting a feedback signal generated from the defect detection line according to the defect detection signal, and determining whether or not there is a defect in the at least one drive power transmission line based on comparison between the defect detection signal and the feedback signal.
