Abstract
A LCD device has a decreased number of required transmission lines. The first interface circuit, which is provided in the controller circuit, receives the polarization reverse signal and the horizontal scanning signal in parallel in such a way that the polarization reverse signal and the horizontal scanning signal have their active periods at different timings. The first interface circuit generates a serial signal from the polarization reverse signal and the horizontal scanning signal, and transmits the serial signal to the data electrode driver circuit by way of the transmission line or lines. The second interface circuit, which is provided in the data electrode driver circuit, regenerates the polarization reverse signal and the horizontal scanning signal in parallel from the serial signal.
