ABSTRACT:
A display device includes a plurality of data drivers which are cascade-connected, and prevents variation of the duty ratio of a signal caused by accumulation of errors. In each of the plurality of data drivers: a first input circuit receives a first signal supplied from outside; a second input circuit receives a second signal supplied from outside, in response to the first signal received by the first input circuit; a signal processing circuit performs signal processing based on the second signal received by the second input circuit; a first output circuit inverts the first signal received by the first input circuit, and outputs the inverted first signal; and a second output circuit delays the second signal received by the second input circuit, by a predetermined amount, and outputs the delayed second signal.
