In a display device using a demultiplexer, two power cables for transmitting external power supply voltages to a display device are formed on the top and the bottom of a substrate, and are coupled to both ends of vertical lines for transmitting power supply voltages to pixels in the display area. Power supply points are respectively formed on both ends of the two power cables and receive external power supply voltages. Accordingly, voltage dropping generated in the vertical lines and the power cables is reduced.
