Abstract: A display device includes a printed circuit board (“PCB”), a ground pad disposed on the PCB, a display panel including an upper substrate and a lower substrate, a touch sensor including a touch pattern directly disposed on an upper surface of the upper substrate, a main flexible PCB including a touch line which connects the upper substrate and the PCB to each other to transmit a touch signal generated from the touch sensor to the PCB, an upper ground pattern disposed on the upper substrate, and an upper ground line which connects the upper ground pattern and the ground pad to each other through the main flexible PCB.
