1. A display apparatus comprising:
a display panel comprising a gate line and a data line; and
a plurality of flexible printed circuit boards connected to one side of the display panel,
wherein each of the plurality of flexible printed circuit boards comprises a gate driving chip configured to apply a gate signal to the gate line and a source driving chip configured to apply a data voltage to the data line,
wherein each of the plurality of flexible printed circuit boards comprises:
a first layer on which a first signal transmitting line group connected to the source driving chip to transmit the data voltage to the data line is disposed; and
a second layer on which a second signal transmitting line group connected to the gate driving chip to transmit the gate signal to the gate line is disposed,
wherein the first layer and the second layer are different from each other, and
wherein the first signal transmitting line group transmitting the data voltage and the second signal transmitting line group transmitting the gate signal overlapped and cross each other.
