Abstract
A display device includes a phase comparator which compares whether phases of two signals which are input are different from each other or not; a counter circuit which counts the number of the cases where a phase shift is detected in the phase comparator; and a phase shift circuit which can output a signal in which the phase shift is restored by shifting a phase of one of the two signals in accordance with a degree of the number of phase shifts which is counted in the counter circuit.
