A display device includes a skew compensating type data receiving unit for delaying clocks received in response to a program signal, comparing the clocks delayed thus to compensating clocks, setting an internal delay amount according to a result of the comparison, and delaying and forwarding a low voltage differential signals according to the delay amount set thus, a clock receiving unit for delaying the clock received thus by a fixed delay amount and forwarding the clock delayed thus as a compensating clock, a clock generating unit for generating a data restoring clock by using the clock delayed thus, and a data restoring logic for restoring the low voltage differential signal delayed at the data receiving unit in synchronization with the data restoring clock, thereby compensating for an internal skew taking place at the data channel which receives a low voltage differential signal.
