Abstract

A display device includes a display panel, a conductive layer disposed under the display panel, a first flexible printed circuit board including a first substrate portion having a side connected to the display panel, a bending portion extending from the first substrate portion, and a second substrate portion extending from the bending portion and disposed under the conductive layer. The second substrate portion includes a first sensing pattern. The display device further includes a coupling portion disposed between the second substrate portion and the conductive layer and coupling the second substrate portion and the conductive layer. The display device further includes a driver chip electrically connected to the first sensing pattern and configured to detect whether the coupling portion has been separated from either the second substrate portion or the conductive layer based on a capacitance that depends on a distance between the conductive layer and the first sensing pattern.
