Abstract: A display device which transmits display data to drive circuits which drive a display panel using low voltage differential signals have input circuits which are hardly influenced by noise. To transmit the low voltage differential signals under the same condition, low voltage differential signal lines are formed in a zigzag pattern so as to make the lengths of the lines equal. To reduce the influence generated by the overlapping of the zigzagged low voltage differential signal lines and the drive circuits, level shift circuits are provided to the input circuits so as to make the input signals assume a stable operation level.
