Abstract
The embodiments relate to a display device that includes an input terminal through which a feedback voltage of a high-potential driving voltage is received from a display panel. An output terminal is included through which a high reference voltage and a low reference voltage generated on the basis of the feedback voltage are output. A flexible printed circuit board (FPCB) includes at least one capacitor connected between the input terminal and the output terminal.
