Abstract
A liquid crystal display device includes a liquid crystal panel comprising a first substrate and a second substrate, a seal pattern arranged in the edge provided between the first and second substrates, and a liquid crystal layer, a plurality of first electrodes and second electrodes crossing each other and arranged in the seal pattern on an outer surface of the second substrate, a pad electrode for the touch panel partially overlapping the seal pattern on the outer surface of the second substrate, a pad electrode for the liquid crystal panel arranged at the outside of the seal pattern on the first substrate, a chip-on-film (COF) connected to the pad electrode for the liquid crystal panel, a printed circuit board for driving the liquid crystal panel, connected to the chip-on-film, a routing line to connect the pad electrode for the touch panel to the first electrodes and the second electrodes on the outer surface of the second substrate, and a flexible printed cable connected to pad electrodes for the touch panel, to receive driving signals of the first and second electrodes, the flexible printed cable connected to the printed circuit board.
