Abstract
A liquid crystal display device includes a liquid crystal panel; a plurality of data drivers for applying, to the pixel elements, graduation voltages corresponding to the display data; a gate driver for selecting a pixel element to which a graduation voltage is to be applied; and a liquid crystal control circuit for controlling the data drivers on the basis of a transfer clock. Each data driver includes a reproducing circuit for reproducing the transfer clock input to the data driver such that the deviations between the duties of the display data and the transfer clock input to the data driver and the duties of the display data and the transfer clock output from the data driver become small, and for generating a latch clock, and a latch circuit for latching the display data input to the data driver.
